Arduino Tutorial 33: Understanding How to Control Servos with a Joystick

You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:
/ paulmcwhorter
In this project we will control the position of two servos using a joystick. The project also incorporates a buzzer which is activated if the joystick knob is pressed down. We show the math that allows smooth and easy control of the servos.
You can get the kit I am using for this series at the following link:
amzn.to/2I7N4Ek
Also, you can get nicer servos than the ones in the Elegoo kit here. These are the good ones I use in most of my projects, and will .
amzn.to/2Ix8ATa
OK, also you can follow these lessons on our WEB site. Here is this lesson:

Most Arduino forums/social media are recommending Paul McWhorter when beginners ask where they should start. Well done Paul! BOSCO!

[@eyoscarygc2019]

i am following your lesson without elegoo because of my parents can't afford it but i'am studying hard enough to be amazing programmer thank you paul you are helping me so much

[@robertmckelvey3091]

Did you ever end up getting you a Arduino set to play around with

[@jacobbedard9350]

In case you don't hear it often enough, you're awesome at this. Thanks for these videos!

[@paulmcwhorter]

Glad you enjoy it!

[@fungaifakazi]

i hope Basco is still around and alive by this time , Long live Paul McWhorter!

[@Bob-zg2zf]

KZbin is home to various outstanding IT vloggers. I've watched, subscribed and unsubscribed many. Paul remains the top one I need to constantly follow. Not because of his skills, but for his past achievement and mentality. Thank you for making me smarter.

[@olegvelichko1659]

Bob I second that motion.

[@chadestell745]

He is a great teacher of the very cool Arduino system!!!!

[@tj9382]

Totally agree.

[@waelal-halawani8056]

what past achievements do you mean?

[@TheUnofficialMaker]

@@waelal-halawani8056 Watch his other videos and you will discover!

[@tomreese9127]

I flew RC planes in the 80s,found 3 servos in the basement and they still work. Hope Bosco is safe from Corona.

[@gawielagrange4786]

Hi Paul. I built the setup with two servos in a pan-tilt kit I bought from our local botshop. I used a laser transmitter module (KY-008) on the top of my pan-tilt kit and connected it to the pin that was originally connected to the buzzer. I was able to shine my laser all over the ceiling by controlling it all with the joystick. Great fun! Thanks for a great course!

[@SteakBackD]

Bosco! Thank you so much for all the amazing tutorials. Having so much fun with all the small projects. P.S as a mechanical engineering student, these projects are even more relevant! :)

[@khushidhingra6524]

"BOSCO" I think that Paul is highly mistaken we love math And if you are reading this, please don't end this series It's a humble request

[@kenspyder1394]

Hey Paul. Great tutorials. I'm a newbie to the Arduino world, and although I'm 65 I feel like I'm back in school again. Thoroughly enjoying your animated videos. Say hi to Bosco for me!

[@daveflatters4981]

I’m also 65. I used to work in IT and I’ve dabbled with Arduino and Python in the past. These lessons and Paul’s Python course are very good.

[@waynedoman4165]

Bosco! Paul, your lessons bring just the right amount of challenge and humour that keeps you wanting more. Ps. Keep the maths coming, it is really good to get a full understanding 🙂

[@josephdscordio2862]

Thanks Paul , it worked for me without that math equation and i used just one servo cause i don't have two or extra and also i did it without the buzzer but i compensate it , with a Happy blue LED only for a special occasions as this, here's my code below : #include Servo myservo; int Vrx=A0; int Vry=A1; int Xval; int Yval; int Switch=8; int Sval; int analogvalue; int servo=6; int dt=300; int LedB=2; void setup() { // put your setup code here, to run once: Serial.begin(9600); pinMode(Vrx,INPUT); pinMode(Vry,INPUT); pinMode(LedB,OUTPUT); digitalWrite(Switch,HIGH); pinMode(Switch,OUTPUT); myservo.attach(servo); } void loop() { // put your main code here, to run repeatedly: analogvalue=analogRead(Vrx); analogvalue=map(analogvalue,0,1023,0,180); myservo.write(analogvalue); delay(dt); //Serial.println(analogvalue); Xval=analogRead(Vrx); Yval=analogRead(Vry); Sval=digitalRead(Switch); Serial.print("Value X= "); Serial.print(Xval); Serial.print(" Value Y= "); Serial.print(Yval); Serial.print(" Value Switch= "); Serial.println(Sval); if (Sval==0){ digitalWrite(LedB,HIGH); } else { digitalWrite(LedB,LOW); } }

[@DanTran-if2jt]

Bosco! "because we do math" lol :)) This episode is so much fun.

[@paulsmigel857]

Bosco. I am watching every episode from 1-33 so far. And will continue to the end. It’s not easy, especially the math, but I am getting it done and I don’t go further until I am successful. Really learning a lot by trial and error. But I just love the challenge. 👍👍👍

[@drbirdleaf2574]

Tell Bosco to keep doing good work protecting one of KZbins greatest gifts. It’s kind of fun to watch how there’re fewer comments on each video the further along we get. It gets me thinking about how things come up in life and some things get put aside, sometimes to be returned to and sometimes forgotten about. I myself have things coming up that I’m going to have to take a break for a couple weeks to complete some obligations and hopefully return. But I have a couple days until then so I’ll try to get one more lesson in.

[@thefierceninja2557]

First things first, Bosco! Second things second, I put off the lessons that come after this so I could get the HiTech servos that you suggested and it was worth the wait and now I have my first robot arm sitting right in front of me as I'm typing. This is an amazing achievement for me because I now have obtained most of the basic knowledge and skills one would need to re-create the funniest machine in Tony Stark's workshop, Dummy. In all seriousness, this is cool, definitely have to build the full scale one at some time in my life. Thanks for continuing to be a great teacher Paul!

[@sravanimalekar643]

BOSCOO!! You make learning so much fun. I'm a 2nd year engineering student and I hope i become one like you. You are great Paul.

[@muhammadrafiqulislamkhan6994]

You are so much lucky student who gets Paul so early. After finishing my Computer diploma engineering I finally find my Coder God Paul almost 18 years. Those students are lucky who find Paul as a code teacher. Such a great teacher to me. Thank you.

[@MrJohnjamesboyd]

“Bosco”, your videos are awesome thank you so much for making them. I am also an engineer but a civil one, so maths not an issue but love the extra detail on electronics. 33 videos watched in two days I’m addicted I can’t stop, lol

[@grahamovermyer5987]

Bosco! I did this on my own before watching the video! I am excited that I'm starting to pick up on the intuitive process of circuit building and programming once I learned the basics. But I always watch your videos after I attempt to see if you do it differently and or give any tips or advice during the session.

[@paulmcwhorter]

Great job!

[@Fractal_CZ]

Paul reminds me my grand dad 30 years ago. He was so passionate about electronics. He even bought the same Atari800 and we talked to each other (i was 15 then) about Atari basic contraptions. This fact (and many others) keep me returning here. Thumbs up!

[@ericsmith7988]

Pooky is actually called "Putty tape" it is used for sealing windows, vents and other objects that need sealed, commonly used on RV's. Thank Paul ,I am watching all these lessons again. I am learning more because I went a bit too fast the first time, didn't pay good enough attention.

[@yargew]

Eric, Much thanks! I am having to skip around in the tutorials due to a deadline for a project. I ran across Paul referring to Pooky in a much later lesson and have been going nuts trying to find it. I have been skipping forward in the lessons to see where he first used it to try to find out where to get it. Your tip is what did the trick. Thanks againi@

[@ErlankBru]

In South Africa they sell it as Prestik.🤓

[@stephanvb5561]

This project was so much fun. Keep that great work coming Paul. Cant wait for all the new things to learn with you. Bosco!

[@alanfowler3069]

Bosco, Really enjoying these tutorials. Thanks, I'm hooked.

[@nguyentranvantien8028]

Bosco. I did it my self before watching your instruction but i still made it to the end of this amazing, fascinating and engaging lesson.

[@krithikavenkatesan2123]

"Battle of the Servos" lol. I love your videos Paul! and... Bosco!

[@mikemoragne]

Slowly making my way through your tutorials! I know the math isn’t the fun part but I really appreciate you explaining why and how things work. It really helps I’m already dreaming up ideas of things I want to make! I can’t wait to watch the rest!!! Thank you sooooo much for making these! :)

[@fablapp]

2 years after the last commets I am still enjoying these tutorials, and send my greetings to Bosco (hope it is the correct spell)!

[@davidbuckley4912]

I certainly did get to the end. Really enjoying the videos. I hope Bosco is not too busy in his official capacity

[@andywylie287]

Bosco! Another thoroughly enjoyable, educational, life improving tutorial from one of the best teachers out there. Thanks Paul. God bless!

[@paulmcwhorter]

My pleasure!

[@chukwusmart9918]

Bosco! Made it to the end. Amazing tutorials, really amazing.✌

[@TheBrockbencomo]

I just getting ready to watch the stepper motor tutorial. Im watching them all through to the end then starting from beginining doing the electronics part.

[@josegayoso2452]

Thanks Paul for teaching us how to use the Arduino. We see the entire video as the prove, it was nice to meet Bosco.

[@DHRUVGUPTA-ui6sf]

Bosco!!!! Feeling amazed by seeing glimpse of the power of Arduino!!! 🤩🤩

[@Anonymous-yy5qr]

Guis just remember one thing in life... Never mess with "Bosco", he has this "Laser of Death" made from Arduino by which he beats the shit out of the intruders :)

[@waynenicolson5864]

Hi Paul, I was lucky to have spent some time in Bosco's country on and off during 2004 & 2005. I was working between there and the country to the west of there. Having worked in a number of other countries since then I always remember how friendly the people were even though most of them don't have much. I was also fortunate enough to get to do the River Rafting trip on that awesome river that we sometimes see in your background pictures. What an awesome place to stay! Keep safe there in these times! And thanks for the entertaining lesson on the joystick and the Servos! Regards Wayne!

[@michaeljenkins2345]

Mr McWhorter, I recently got a Raspberry Pico and can definitely say, its a bleak learning landscape without your tutorials! :)

[@jasonrhoades4122]

BOSCO!!! I've always wanted to visit Africa. I've heard there are some beautiful places to see. Love this lesson, pan/tilt can be a very useful design. You're givin me even more ideas!!! I'm about to get a 3d printer (still deciding on the right one) and then the sky's the limit! By the time I get through all these lessons, I hope to be able to build and program a whole new world!! If I can dream it, I can build it! Thats the goal!

[@ErlankBru]

Thanks Paul for this most awesome series of tutorials and thanks to Bosco for keeping you and everyone else safe so you could record in your studio with peace of mind🙏. I did some major exam-like revision all the way up to tutorial 30, not exactly done yet, but my curiosity wanted to continue with these MOST excellent tutorials while I'm in the process of reviewing. I've never done programming before, which is why I want to keep going back so I can gain long term memory knowledge.😶‍🌫📚💡

[@user-qs4ti1bh6e]

From a learning standpoint, the components in the kit are excellent. Easy to use and work with on a desk/tabletop top workspace and they make it easy to scale up to larger/more sophisticated projects later on. I'm sure that's how the kit was engineered and they hit a home run IMHO.

[@anilcank]

Buscov looks like a very polite man, thank you for the tutorial Paul really appreciate it :)

[@jonathanmalamy3760]

Paul, we are all here at the end. Bosco sets our minds at ease.

[@ennisyui]

Bosco! I'm very glad that I did it without watching or copying the contents in the lesson. Thank you so much Paul!

[@paulmcwhorter]

Glad it was helpful!

[@hunterpalmer9706]

Dear Bosco, thank you for protecting my engineering Sensei, I bow to you! From, Hunter.

[@donvanote]

IIt took several days as I had to order the servos, and then life etc. But I really enjoyed this lesson and making the servos respond to the joystick. Thank you!

[@muhammadrafiqulislamkhan6994]

I watch your video over and over again. And I would say, you are very special teacher to me. If I become an Arduino programmer, all credit goes you because you the teacher where I learn first this miracle programming. Thanks.

[@toolooselowtrek7523]

I am going to tell my grandchildren about you, Paul. You motivate mathematics like Descartes.

[@Rorschachcollision]

I love how watching the previous lessons really starts to pay off in these lessons. Very easy and logical if you follow along.

[@johnvandenberg2445]

Bosco . Thanks Paul as an Australian Retired Electronics Engineer it is easy but fun and that is the main thing. Really appreciate it.

[@toolooselowtrek7523]

Thanks for those side comments, such as “”Don’t treat servos like fidgets”. So helpful!!!

[@richthofen9592]

You make me be proud for being one of those who understand how to program a joystick with servomotors, also for knowing what BOSCO means and why we are commenting BOSCO!!!!!!!!!

[@hughpatterson1480]

Great video! This one is perfect for students exploring the idea of being able to make robotic devices. I tell my students that they are lucky to have gotten into electronics today, when you have devices such as the Arduino available to them. At sixty years old, I tell them that all we had to work with back in the day were vacuum tubes and breadboards made from our mother's cutting boards and our fathers roofing nails. Of course, they all look shocked when I tell them there was once a world without the internet....

[@paulmcwhorter]

Yes, I am also 60 and in High School I went through physics using a slide rule. People today have trouble believing you can do math using a couple of special rulers latched together.

[@gilnasty82]

Yes, it is hard for them to imagine a world without the World Wide Web!!! I bet most don't even know what that stood for, or remember dial up internet!!

[@calvindeiterich9913]

Bosch - made it through to the end.

[@powersprouter]

Hello Bosco! It's so funny, TopTechBoy reruns are even more fun than watching old star trek episodes all over again. Binge-ing to the end by tomorrow night. 😋

[@dhobonov]

When i was a kid, BOSCO was an amazing syrup that mixed with milk to make chocolate milk. It was great but not as great as these tutorials. Thank you, Paul. It's Christmas here right now so Merry Christmas to you and your family.

[@emoraven88]

Hi Paul. I couldn`t follow along with you on this video because I only have the Elegoo servo motor. But to compensate for that I did a self-assignment to control a servo motor, the brightness of 4 LEDs and the state of a 5th LED, using the joystick. I allowed myself to use different colours of the LEDs as this was a special occasion to me. I made the 4 LEDs to increase their brightness one after another with overlapping when I move the joystick from right to left and to decrease their brightness one after another with overlapping when I move the joystick from the left to the right. I made the servo pointer to point up or down, corresponding with the direction of the joystick and I made the 5th LED (red) to come ON every time I press the joystick in.

[@unknownswords4872]

sir you explained it really nice . this is the first vedio where i had seen someone programming live and explaining calculations bheind the process . i had found your videos for arduino. thanks a lot sir. plz make such intersting and indepth tutorial for students who will to make many good project but lag due to lack of programming and proper guidence. !!!!

[@kirillsanchez5110]

Bosco! Thank you for teaching us joysticks and servos for Arduino!

[@shatterism3329]

Bosco! I can't believe I made it this far, it's only possible because of a great teacher. Thank you Paul for teaching me the way my past teachers cannot. A month away before my first year of being a Computer Engineering student!

[@jackeetyler]

Bosco in 2021, and continue watching... just wish I had teachers like you!

[@terryhoward986]

Hi Paul, Bosco is the word, glad to hear you like Africa we cant wait to get back there again. Thanks for the knowledge sharing.

[@frang342]

Bosco is the answer,I watch all the tutorials till the end. I know math is not the most interesting however I copy all the math equations to a spiral notebook that I have for all my electronics for Arduino. I keep it for reference I could never remember all the little things I learn. I'm new to electronics, as a hobby. I'm 65 years old and I'm getting a lot from your tutorials they are helping me out with the coding part to go with the electronic circuits. Thanks

[@larryshreve9076]

"Bosco" I've been watching every second of each video and enjoying it immensely (even 2 years later)

[@RobVollmar]

Bosco! It took me a week to secure the components and figure out how to mount one servo to another without the putty tape but I got here.

[@richardbritain7435]

Bosco. This was brilliant. After struggling with a few additional bits of my ,own this lesson also reminded me of the '==' command. Thanks for the great lesson.

[@fridaycpc5210]

BOSCO I really enjoy all your teachings. I believe that one day I will be a guru like you. Please keep it up, I love it.

[@santiagoperaza967]

I was able to do it without watching this video .... I could control the servo with the joystick .... so refreshing to see is similar to what you did Mrs. Paul .

[@santiagoperaza967]

[@erikburman530]

I think that by now you know that there are those of us who pay close attention to the very end. So....BOSKO! And yeah that guy looks like he will put up with no nonsense. I suspect that the same applies to your Texas prepper homestead. I'm loving your Arduino tutorials. I'm beginning to feel like I might become a coder!

[@RavensHammer00]

Bosco! Kinda got behind my schedule, had to wait for a pair of servos to arrive in the mail...I got to find a better way to get stuff in the mail, because watching an item sitting in a shipping hub for a couple of days made me want to pull what's left of my hair out! Love your content and your style of teaching, Paul. God bless you for sharing your knowledge with us!

[@bleujaegel]

Bosco. These tutorials are a blast! I have learned so much. Funny thing is that my son was calculating slopes in his 8th grade math class a few months back. I saw this and thought why do they waste time with this? Now I know. Slope calculations are now burned into my memory. Thank you

[@topdowndays]

Bosco. Thanks for the incredible instructions. I usually get about 90-100% on my own but when I'm stuck, I'm really stuck. It's great to have you helping me along.

[@israelkolawole7144]

Bosco is a very vigilant and smart guy during Arduino tutorials

[@EB-fd6rh]

I know these videos are three years old, but I finally did one of your Hw assignments! I discovered the Arduino map function though, so I used that for the servo angles rather than the actual equation.

[@TheSelfUnemployed]

God bless you Bosco! Thank you for protecting Paul! And a million thanks to you Paul! I was laughing out loud when i got my laser to work! PEW! PEW! And Hello to all the new people I see are watching recently!

[@georgemoertle3249]

Thanks Paul.. Bosco is looking warm in his coat.

[@frikkieventer9440]

Bosco. I have done the assignment, but used the " map-function" in stead OT the math. Worked fine. Also used a 3volt laser printer that I could switch on and of with analogieë. From South Africa. Enjoying the lessons with grandson

[@raygarner6366]

One more great tutorial. Got my wires mixed up at first. Then BOOM! Buzzer and all! Success! I did skip the ice coffee and had a nice large hot black coffee instead. Bosco who is properly dressed for Ottawa Canada would approved (it's -10F (-23C) ). Thanks for keeping it entertaining.

[@williamharris5795]

BOSCO I find the arduino lessons very good and appreciate the effort that Paul puts into producing them in a very well regulated rate to allow progressive learning.

[@jonathanlanders9406]

Bosco! For those interested in RC applications, I wrote this code entirely in variables. This allows you to adjust the max/min angle of the servos and the sensitivity of the joystick.

[@haavishbonala10]

"BOSCO" I am 11 and got my Arduino kit yesterday, LOVE YOUR VIDEOS !!!

[@paulmcwhorter]

Good job!

[@adamcurtice3584]

This was a great project. I wound up digging through my scrap boxes and making 3 custom cables for the joy stick and the two servos. after seeing Paul's Servos flop around I decided to screw the bottom servo down to a piece of wood and used plumbers putty (aka pookey) to attach the top Servo. I used a large Alligator clip cover that slipped over the servo arm as my pointer. All this mechanical and electrical effort work great. Unfortunately I made one small mistake in my code that took me awhile to find. Only one Axis would work. I went through my wiring and my code several times. I verified both servos were in fact working. Finally I found that I had typed Xservo.write(WVx); Xservo.write(WVy);. When I changed the second Xservo statement to Yservo all was well in my world once again. ;) Bosco would have been proud. Having lived in East Texas since the eighties I have to say that anything below 60 begins to feel cold to me. Thanks for all your time, effort and energy.

[@iseecrap]

Bosco! I made it to the end. Great lesson and I managed to complete this one on the end of tutorial 31 (except the buzzer!). It's all coming together nicely - thanks Paul

[@paulmcwhorter]

Fantastic!

[@russellford366]

Bosco!!! I never thought I would be able to learn to program! I'm still slow, but I am learning! Thanks, Paul!!!!!!

[@paulmcwhorter]

Happy to help!

[@trumpatier]

Bosco looks like a nice guy. I encountered an extremely stressful error during this project. I set out to power my servos externally, and when I made the connections and uploaded my code, my joystick readings were way off, and my servos weren't responsive. I thought I fried my joystick potentiometer with the external power supply (4 AA batteries in series). Turns out the error was in my code - I accidentally attached my servos to xpin and ypin (the input pins from the joystick) rather than xservopin and yservopin. I found this out by comparing your code from the website to my code, so thanks a bunch for making that available! Everything works perfectly now :)

[@joshuavergara6863]

BOSCO. I am having somuch fun watching your lectures. It brings me back to my teenage years when I was building basic circuits using the 555timer and getting schematic from radio shacks little book.

[@hadi.merati]

Thank you bosco! I controlled 1 servo motor using a twin joy stick on my own because of your teaching skills. I didn't have 2 servos. But for controlling 2 servos I just need to add some repetitive codes and it's not going to be that hard.

[@richardalexander633]

Bosco - Hi Paul went back and completed with the HiTec servos as they arrived a few days ago (but I kept moving through the remaining tutorials anyway as having so much fun)

[@pathvalleyrailroad9277]

I was able to refer to the previous lessons and hook this up before I even looked at the video. Thanks for doing these videos!

[@pathvalleyrailroad9277]

Bosco!

[@adirajchalotra4916]

Bosco! Paul, you are a true legend in keeping all of us watching till the end of your videos! Thank you!

[@dghmrrinn951]

Bosco is the best guard, because he does Math! And, math is VERY important! Paul, you are an amazing teacher, and quite the entertainer. Thank you for doing this series. And, I watch to end, everytime! Cheers, from the east coast of Canada!

[@paulmcwhorter]

Wow, thank you!

[@scrappybobbarker5224]

Bosco! Thanks for the great lesson. I enjoyed the X axis and Y axis servo project. I decided to mount an LED light on the side of the Y axis servo horn, and when you press the joystick button, the LED comes on, and there is a oscillating laser sound coming from the buzzer. Thanks again for all the time and effort that went into making this video.

[@CarolinaDGF]

"BOSCO!" These lessons continue to be entertaining and educational. I was able to hook up my single servo before watching the lesson. Will go back and add the second servo when Amazon delivers it. Great work Paul!

[@paulmcwhorter]

Great to hear!

.. BOOOOOOOM to BOSCO😎... Since I did not get my second servo on time and my buzzer was faulty , I decided to replace them with two LED lights (yellow and green) where I controlled the first servo with the X-direction of the JOYSTICK and then I analogWrite to the green LED so that its brightness increases and decreases by Y-direction of the JOYSTICK and finally the yellow LED comes ON when the SWITCH of the JOYSTICK is closed and then It is OFF when SWITCH of the JOYSTICK open. THANKS A LOT MR PAUL.

Came for the Arduino training, stayed for the math lessons. If I don't have the slope of a line formula and the point slope formula memorized by the end of this series, I will be very angry with myself. Only had one servo but made it work both ways with WVx and WVy just for fun. BOSCOE!!!
