Arduino Tutorial 36: Understanding How to Use Tilt Switches in Your Projects

[@brankostrbac5931]

I am electrical engineer, this is the best tutorials I have ever seen!

[@ayratkutlushin5252]

String birthday = "Happy Birthday!"; String granddaughter = "Gabriella"; void setup { serial.begin (9600); } void loop { if (11/12 = your birthday && granddaughter=coming home) { serial.print(birthday); serial.print("clue word"); serial.println(granddaughter); }

[@AhmedMohammed-kz6ej]

hahahah this is so cute

[@Vivalavidapool]

haha, I second that! Great video!

[@ac8228]

That's wrong, it should be == because it's conditional

[@terrymiller1600]

Paul, I also am an Engineer but, I went to school in the age of vacuum tubes. I was the RTU Engineer at my local electric utility. Your videos are very professional informative. I do watch every lesson to the end. I also spent 7 years in the Ivory Coast as a Peace Corps volunteer. Thanks for the wonderful classes. I do really appreciate the insight. BTW, Happy Birthday and enjoy your time with Gabrella.

[@abdulfx5030]

GABRIELLA! Thank you engineer. I have an electronics engineering degree. Thank you for giving this free tutorial. It was one of the best tutorials I've watched.

[@Chris_Bro_aka_MR_PLAT1NEM]

GABRIELLA! I'm currently on day 3 of going through these tutorials and I have done them all the way through including the homework in between. This stuff works!

[@FEDERICO-tc3wn]

Gabriella!

[@dema3619]

you are incredible fast! congratulations, you are a really fast

[@billlaird7332]

GABRIELLA! I'm watching all of your Arduino tutorial videos in order and always to the end. I don't do every assignment, but when learning a new important point, I do the assignment to reinforce the learning. You are a Master Teacher and your teaching style is the best I have ever experienced. I have completely understood every lesson. I especially like the in depth explanations of the combination of software, hardware, and physics. Well done, sir.

[@sumantakumardutta986]

Done the assignment by myself after pausing the video. Got it right in the first shot itself. Really had fun!!!😃😃😄

[@Rorschachcollision]

I am a programmer and engineer, so have very little patience for these things - but the wife had to point out that you and I are both Scorpios. So happy birthday, great teacher, and know that I will follow your tutorials always to the end, with coffee in hand.

[@MrSylsound]

"Gabriella !" Awesome videos by the way! After only a few days of owning the Elegoo kit, I made it to lesson 36 and was able to do the homework, and it worked! I'm super happy :) Thank you!

[@kaindradjoemena7789]

Awwww Gabriella looks cute Happy birthday Paul! I just made a robot the other day that follows light. Nope, I did not copy anyone’s code. I did it myself. Thank you

[@bilbo593]

I am a retired Electronic Repair and did my course back the 70's with AWA Corp and Industrial Electronics . I am enjoying keeping my mind active and re learning things. I closed down my Repair Business back in 2008 and since then I have lost touched with everything electronics and all the latest innovations. Gabriella was happy to catch the plane to come and see you. And a very Happy Birthday!!

[@alecgriffiths790]

Gabriella! And yes, I was able to figure out how to set up and program the LEDs with the tilt switch without having to simply copy what you were doing... for once, haha! Hopefully that means I'm finally figuring this stuff out. This was a great tutorial, and I'm looking forward to watching the next one.

[@tonygolden8622]

Hello again Paul. Now that I have completed the project and watched the end of the lecture it is time to mention Gabriella. I have watched all of your videos, some more than once. I have completed all the projects, got many of them right, made mistakes on others, but learned something and had fun with all of them. I see that you have many other courses, enough to keep me busy for a long time. It is hard to imagine all the work it took to produce them. I really like the spontaneous feel, like one is working along with you at the same time, and your sense of humor is spectacular. Now on to lesson 38, 39, ……. Tony

[@MajdMazin]

Gabriella. I have been watching till the end every single one since the beginning. You have been a godsend good sir. I highly appreciate all the effort you put into these tutorials, it is not lost on us. You are a truly exceptional teacher and a delight to watch and learn from.

[@banyincam]

I showed my son the green on tilt red project and he was amazed. I explained that it was as simple as two connections and a little ball. I even unplugged it and rattled the ball inside. He then suggested a magnet and sure enough, the magnet doesn't even have to touch it. It simply gets close and the lights change color. Gabriella!

[@emiliomartineziii2980]

At the start of the video I paused and built the entire thing and got it to work by myself!

[@johnmills353]

Hi Paul, Gabriella !! Following your whole series of newer Arduino tutorials, just finished No 36 (tilt Switch). I always watch them to the end, I have about a 50% success rate with the assignments. You have got the mix of practical and theory just about right in my opinion.

[@cmartin6126]

Hey Mr.Paul! Another glorious video tutorial. I am very grateful for the hard work that you put into these amazing tutorials. Keep up the good work! Gabriella looks excited! -STILL not Carole, just her son.

[@JohnyRalte]

Gabriellaaaa!!! Not only did I watch all your videos from start to end, I have watched some videos twice. You are a good teacher.

[@paulmcwhorter]

Thank you so much!!

[@muhammadrafiqulislamkhan6994]

Happy Birthday. God bless Gavrialla. I do not know how many times I watch your video to understand your project. Every time a new thing comes out to me. Your debugging process is wonderful. It helps students where they are made mistake. Today I learn why I put TiltVal in place of TiltPin into serial.println because we already have tiltPin=2. I know it easy for everyone to undetstand but it is really difficult in past to me but today my legendary teacher Paul all clear to me. Thanks for everything Paul. God bless you.

[@soup2ru433]

Really wish I had you as a teacher when i was in school, I might have just paid more attention.

[@yasins8713]

i figured out the error and homework by myself, i also used the mini breadboard for the tilt switch so i could move it with out reducing the visibility of the leds. gravrela

[@tonygolden8622]

Hi Paul. I’m just another old dog trying to learn some new tricks. You are a great teacher. Thanks for your generosity of spirit.

[@paulmcwhorter]

Glad to help

[@satisfactoyz]

Today's homework was much easier to complete without instruction. And it was your birthday! Lucky man to have such a beautiful grand-daughter! Thanks for another great lesson.

[@johnmichaeljones2600]

Belated “Happy Birthday”! Another great tutorial. Gabriella.

[@delroybarnes2041]

Made it to the end ans saw "Gabriella"; see much more than 3 minutes worth.

[@agonslay9173]

3 years late but Happy Birthday!! Also Gabriella looks like an angel. I thing you are the sweetest and coolest grandpa that everybody would want

[@timothyflanagan7775]

All the info you put into your videos; does NOT go to waste with this student

[@TheUnofficialMaker]

i use this tilt switch with a 555 timer to light an led and installed in a house shoe so I can see at night if I have to get up.

[@musicalhamsa5892]

the 3 dislikes are the people who dont like coding

[@geraldinecommowick]

What is there to dislike? I don't get it.

[@benthompson6118]

Gabriella. I recommend all of your video tutorials to anyone who asks me where to learn arduino, pi, fusion360, or python.

[@rodchristen2705]

I watched to the end and did my own coding!! Thanks for your help. I hope you had a great time with Gabriella as she was coming to see you. Grandkids are great!!!!!

[@dannycollins5698]

This was fun. I taught this to my 4 boys and wife. It was fun letting them hold the tilt switch. I asked them what they felt. It was fun to see them enjoy learning. 4, 6, 8, and 10 are the ages of my boys. This is so wonderful to take the code and to the physical world. It is fun thinking about what projects we can do with all that you have taught me. My boys have ideas of what we can do together. Look forward to paying it forward to my boys and may a school someday! We started with an experiment from the Feynman Physics lectures/exercises this morning and then did this. Wow -- how blessed I am to study Physics with Feynman and Computer Science with you Mr. McWhorter!!!

[@paulmcwhorter]

Great that you are making this investment in your boys. Well done!

[@eddiedunseath9063]

I also used else instead of 2 if's on this. I jump back into your lessons to check things as I'm doing my homework (sometimes for only a few minutes, as you say), because I started your most excellent tutorials only 2 months ago, following my 80th birthday Arduino gift, and my brain velocity is much lower than it was 60 years ago! Also in this project i stuck my tilt switch to my stepper motor cardboard arrow (motor fixed vertically), connected using a pair of female/male wires. It switches the red/green LED's, but also controls the stepper motor direction, clock/anticlockwise, like a wiper blade. Thanks for your really excellent lessons Mr Paul. I used to live in Addis Ababa, love Africa and its wonderful people! Hi Gabriella !!

[@angusclarke8592]

Thanks, Paul. My Maths is actually non-existent so I'm very slow at working these things out. But trying a new thing in my late 60's gives me a new challenge in life. Welcome to Africa. I see you've now re-located. Very Brave at your age, but obviously Higher Hands are leading you. And Gabriella is a sweetie. So Cute.

[@israelkolawole7144]

Hi Gabriella, Mr. Paul has taught me a lot and am very grateful so give him lots more applause

[@diessos]

Gabriella..... took a few months off due to other commitments. But was able to easily do this on my own. Really like these videos. I am finally understanding how all this works.

[@johnryall5711]

Many Happy Returns Paul, made it to the end AND made it work! Granddaughters are precious, enjoy your time with Gabriella.

[@joelmagana4227]

Funny enough, I wrote my own code before looking at yours, but neither mine nor your code seemed to work, so I was just about to get ready to take apart my circuit. Then I realized that I had never grounded my red LED. Now, it works like a charm!

[@zachhamersley967]

Don't understand why people wouldn't finish the videos, but I like to understand how things work. Make it to the end every time, I thought that was the point. Did the homework on my own the same way you did, I think I'm starting to get this stuff. "Gabriella". Thanks for the videos Paul!

[@victorlove3558]

Gabriella, I am very appreciative of your easy to follow and understand lessons. I'm in my seventies and doing Arduino for the first time.

[@paulmcwhorter]

Wonderful!

[@kirstinlee6838]

Happy birthday! Your granddaughter Gabriella is adorable! I was so excited to do the homework by myself. Thank you so much for these videos.

[@gilnasty82]

GABRIELLA is precious!! Truly a gift from God!! :-) I can't believe average view time of your videos is only 3 minutes!! WOW!! I find myself anxious for more!! Can't wait to start the next lesson! HAPPY BIRTHDAY PAUL!! (late by a few years sorry)

[@Mr_Jonathan_Greer]

I really like the homework. It forces me to recall things that I have learned and figure it out on my own. I really enjoy the way you do these lessons! Great work!

[@digitaldoubter]

Gabriella!! I'm a computer science student who has a passion for building things with my hands, your tutorials have been awesome and I'm really thankful for this series!

[@aaronmilliman7685]

Seeing the children healthy and Happy is the best birthday gift ever! Happy Birthday and Gabriella looks so happy.

[@jaydusterhoff2795]

Gavriella. Struggled with the homework for a bit until I realized I used the wrong brackets. Worked great after that lol. Happy very belated birthday Paul, hope you had a great day.

[@amiamso]

GABRIELLA, I just want to say THANK YOU for all your videos. Yes, I watch them to the end, and then go back and pice-meal them into the code project i'm working on. Oh... and no, I don't do my homework. I take a coffe break with you. Thanks again for all that you do.

[@dubrocadidier4583]

GAVRIELLA .... This Homework was cleared fast 😀 thanks Paul. I have been watching all your videos to the end. Most times I replay as many times as possible to understand the concepts. Especially the ''PUSH BUTTON AS TOGGLE'' lesson.😄

[@CK-sv8fc]

Happy Birthday Paul!! --Gabriella-- As soon as I heard "pause this video" I immediately went ahead and did the homework.

[@MrBrentc74]

Gabriella looks like a bundle of joy! I saw the mistake as you were typing it. Still need to wrap my head around the toggle switch logic, but was able to do the homework just fine. Thanks for the effort you give in sharing this knowledge. We are truly blessed to be able to learn this because of beautiful people like yourself!

[@daniel-yd7bq]

Gabriella! You are the best teacher I have ever had, I'm glad you made this series

[@paulmcwhorter]

Wow, thank you!

[@daniellehwing4667]

Gramps Paul must be so proud!!

[@HASANALI-wd1yl]

happy birthday Mr. McWhorter, you absolute legend!

[@davidkeynton3402]

Yes, I got to the end and completed the homework before watching how you did it. Am enjoying all your videos. Gabrielle.

[@derekpalmquist594]

Gabriella! Was able to do the homework on my own. Just proof of how awesome of a teacher you are! Keep it up Paul!!

[@paulmcwhorter]

Great job!

[@ABAT58]

Thank you very much, Paul. That is because you are printing the pin not the value you just read. Thank you for your trick. You are a wonderful instructor.

[@jeffnixon8338]

Gabriella. Love your explanation and coding, Paul. I’m Jeff from Australia

[@thelocal911]

I always do the homework Paul. And, you're right, it really does help. I coded mine to take three readings 500ms apart. You can shake it all day without triggering the red LED, but one second after it tips, boom. Red Light!

[@hbar2028]

Gabriella. Been watching all your videos beginning to end at work on my breaks. Then when I have time at home, I redo them again step by step. Great videos sir! Learning so much.

[@ErlankBru]

Thanks Paul, I enjoyed this project and watched until the end and was also able to program the homework myself. Gabriella looks very excited to go see her grandpa!😀

[@lefterisdagkalakis3016]

Paul, I did the mistake of the equal, instead of the equal equal. I was breaking my head to understand why it wasnt working, and then I eventually understood it. I hope that eventually I learned it. GABRIELLAAA!!

[@TheCourtoh]

Gavriella. I don't have a tilt switch in my kit but I am listening along to the video.

[@user-ys6bc7yh7z]

Thank you for the great series! The deliberate mistake was that we were reading tiltPin, instead of tiltVal!

[@charlesouma2803]

I was able to go back and finish the assignment on my own without watching the whole video. It worked, and now that i have watched to the end....Gabriella❤❤

[@paulmcwhorter]

Excellent!

[@Jobbe59]

Gabriella! I watch all your lessons to the end. Don't want to miss a second of them.

[@alexguidi2345]

Hi Gabriella, I actually did the project by myself before you gave the homework as when you started the video and showed the tilt switch and the two LED’s I knew exactly where this was going 😂

[@user-po3zo6dj7b]

"Gavriella". Off course I always follow your videos to the end. Well, I did my homework and I did it well after two mistakes ("Red" instead of 1, "Green" instead of 0). Always fun to follow your Lessons.

[@josemurillo227]

Gabriella!! I am 3 years and change in the future wishing you a very late happy birthday PAUL! haha. Also, I was able to do the homework on my own the only thing different I just put the else statement instead of another if statement. Great video once again !!

[@mystreteacher]

Gabriella. Thanks for putting this series together. I'm an Assistive Technologist for students with disabilities and I'm just starting down the Auduino path so I can make more customized and sensitive switches for the students I work with.

[@koomber777]

I'm happy to admit that going through these lessons that I have printed the pin rather than val many, MANY times.

[@Zpheme12]

you are one of the greatest you tubers for electronics education. (Gabriela)

[@jabber2824]

Love this course! And yes did my homework and watch til the end. I bet Gabriella is having her own Arduino kit by now. Cheers!

[@williamlemley4333]

Gabriella, homework completed. Added a delay in the loop to avoid intermittent flickering in the closed position.

[@sapphirereaper1252]

Gabriella! and that's for every video so far. This series is absolutely brilliant!

[@utahasweseeit]

I made it to the end and did the homework on my own. Gabriella. Grandchildren are the best.

[@vincentgirard8045]

This wasn't the first time that I have attempted the homework but it was the first time that I successfully completed it without having to cheat. Thank you for all your work.

[@williamluety6430]

This was a great problem which I solved with using Your Tutorials and, of course an Arduino kit. A motor driven arm rotate starting at -10 degrees all the way around 360 degrees to +10 degrees and then stop. Of course after it stops you will need to rotate it back to the -10 degree start position. Tilt switch are not used due to repeatability problems. We also couldn't use limit switches. If you would like to know my solution just ask. Only tutorials 1 thru 17 were needed.

[@pudgepatenaude3481]

Boom, homework done. Gabriella looks very happy to be coming to see you.

[@noobcoderandmaker]

I'm watching Paul!. Enjoying the series so far. I also made it to the end, as I have with all your videos.

[@parulchhabra2939]

Happy Birthday Mr Paul, seeing the video 2 years after you posted it and coincidentally on your birthday date 🙂. You are an excellent mentor so can't miss any part of the video and yes saw Gabriella !!!!

[@akm5611]

Hi Paul, I think your lessons are great. I have had some programming in C about 25 years ago and it seems to be like riding a bike, most of it came back. Thanks for the videos, having a great time with my Arduino.

[@paulmcwhorter]

Great to hear!

[@chernoblyat1901]

Gabriella is lucky to have someone like you sir!

[@user-mx4ek3jf8s]

Gabriella. I watch all tutorials to the end. They are so informative and easy to understand. Happy birthday.

[@audreyflores243]

Made it to the end. Gabriella (I hope I spelled her name correctly) I was able to do the homework on my own, along with the servo/joystick homework. Having a great time. Hope when you made this video you had a great birthday. Thank you so much again for the great content.

[@yigitpar6492]

Gabriella! Not a single second is wasted by skipping it. I have very limited time during the day because of work+parenting, but I am here to learn, not to memorise some stuff for a day or two. Hoping one day I'll tell/show someone what I learned, so I gotta be prepared :) Thanks a lot

[@alanfowler3069]

Tilt Switch working, think I'm finally getting to grips with this coding. Happy Days. I Know I'm late to the class, but really enjoying learning new skills. Thank again.

[@paulmcwhorter]

Nice work!

[@kevinshaver5613]

The project was an easy one. After the stepper motor lesson,this one was welcome!

[@Aliguibrisa393]

Gabriela I watch your videos all times to the end thank you for your time

[@caltech-wirewizard]

Gabriella !! Yes, I go from start-to-finish on each video in succession and I enjoy them! And YES, each and every assignment.

[@paulmcwhorter]

Wonderful!

[@tomeasley5979]

Nice that Gabriella could come and visit you! I am sure you enjoyed the visit! and Happy Belated Birthday as I realize the time delay of making the video and us viewing it.

[@paulmcwhorter]

Thanks so much! 😊

[@philnewman1110]

I always make it to the end even if I have the video two or three times (Your benefit Paul) and I worked out the fault that was in there before you showed it! Im so pleased with myself! GiddyUp Gabrielle!! Thanks Paul.

[@gladbod300]

Thanks, post-Happy B-day! As a fun challenge I made the code so that it allowed vibration using two variables. The first was an average of 30 shorts or open circuits using a for loop. This produced either an int of one, or a float less than one. The other was produced with an if statement that counted the number of consecutive averaged ones (shorted states/cycles). So if 20 consecutive averaged ones were counted then it would allow the shorted state of one to pass through the if statement and trigger the light (if (ave=1 && count > 20) etc...). I based this by vigorously shaking it, which usually triggered 4-15 consecutive averaged ones. If I tipped it over, then it instantly (to the natural eyes) counts 20+ consecutive averaged ones (or shorts), and it gets triggered.

[@davedave3631]

Happy belated birthday, Paul. You probably won’t see this but I really enjoy your tutorials. I wish I would have found them sooner. Who knows, maybe I would have been so much further ahead by now if I would have. Two thumbs up, sir.

[@paulmcwhorter]

Glad you like them!

[@Sam-rz5hw]

And i am watching this lecture on my birthday!!

[@Shalfatk01]

gabriela is pretty name :) . side note. most of those short views are because somebody come back and seek only the part of the video that didn't remember. new viewer can also speed up the video up to 2x speed. so it is half of the time . those are factors why those numbers may seems to be "low" but dont worry. those videos were made two years ago and i just stumble across them :D and i love all of them. it is exactly the way i like to learn. you made great job by making those videos.

[@bill6590]

Made it: Gabrella. Good tutorial. I tried to use the else command instead of a double digitalWrite command. I got a very weak green and red LED lite. But, with the doubleWrite commands. I got a bright LED lite. Strange, not sure what happened. I got it right except I forgot ==. I just used 1 =, and forgot my penmodes. I always go all the way thru the tutorials and do the homework first. HAPPY BIRTHDAY PAUL!

[@yepitsmebob88]

Gabrialla, I did the home work and the mistake on my own. Awesome lesson, keep it up.

[@leifpernstig3200]

Hi Paul, and happy birthday. Hope Gabriella comes to visit! And yes, I watch all your excellent tutorials to the end (36 so far!)

[@arseivan]

Hey Paul, thank you for another lesson (Gavriella)! I did this one before watching you doing it. Below is the code I ended up having. Nice way to simplify the if statements here - since we read 0 and 1 already we can incorporate these values in the digitalWrite statements: int greenPin = 8; int redPin = 9; int tiltPin = 53; void setup() { pinMode(greenPin, OUTPUT); pinMode(redPin, OUTPUT); pinMode(tiltPin, INPUT_PULLUP); Serial.begin(9600); } void loop() { bool tiltVal = digitalRead(tiltPin); digitalWrite(redPin, tiltVal); digitalWrite(greenPin, !tiltVal); }
