How to Use a Joystick with Arduino (Lesson #13)

[@komplikuotas1691]

Extremely underrated. Don't stop making these videos, they're really helpful.

[@theKangarooConspiracy]

Seriously, these videos are gold. Thanks so much for making them and please don't stop. You're walkthroughs are easy to follow and you're always very clear.

I'm a beginner but i love how short and helpful this video is thank you 👍👍

[@Mifftymc]

This was an amazing and useful tutorial and it helped me so much! thank you!

[@KambySchmidt]

GREAT videos but how do you connect things with the other type of joystick.

[@humamalherbawi4732]

Thank you very much Today I watched 13 videos and you taught me Arduino within 5 hours I have a question My joystick is different. it has 5 pins, GND, +5V, VRx, VRy, SW

[@Science.Buddies]

Hi - glad you found our tutorials helpful! You'll need to look at the documentation for your joystick to figure that out. Some joysticks are "clickable" and you can push them down to also act like a button. My best guess is that VRx is the voltage for horizontal motion, VRy is the voltage for vertical motion, and "SW" stands for "switch" which closes when you push the joystick (so it will act like a button - see our tutorial on that earlier in the series), but I can't say for sure without seeing the datasheet for the joystick.

Wow super video!! 👌🏼 Thanks :)

[@user-tj5uf1iw6f]

thank you, everything is clear. but there are not enough electrical diagrams in the lessons

[@Science.Buddies]

Sometimes written instructions for projects on our website will include circuit diagrams, since these videos are for beginners we usually stick with the breadboard layout and are not teaching circuit diagrams yet.

[@kpieceemmry3387]

@@Science.BuddiesYou can still attached circuit diagrams to it cos it better stimulate the learning for both beginners & intermediate. I want to know if all the joystick terminals are used in this project? Like does it have more than LR, UD? How about rotating, SW? Etc thanks 🙏 for a wonderful explanation alwys in your videos

[@johndysalomon6125]

Isn't it better to also put deadzones on the map functions?

[@Science.Buddies]

Yes, that is useful to avoid drift.

[@Drxxx]

i recieve it per post, and i can´t wait to test them :D great modul, btw , cool channel !

[@Science.Buddies]

Thanks! Check out our playlists for lots more Arduino tutorials and electronics projects (as well as plenty of projects in other areas of science).

[@noobmaster_139]

I’ve never used these but are you able to make separate joysticks the way you did and connect them together?

[@aomacthi7860]

bro, what's joystick you using ?

[@lego_films6971]

what jumper wires are you using for the joy stick the orange and black ones

[@Science.Buddies]

They are flexible male-male jumper wires like these www.amazon.com/HiLetgo-195pcs-Electronic-Breadboard-Universal/dp/B00M2GH5HG/

[@ParkusYT]

@@Science.Buddies Do the colors actually matter or is it just for you to identify what does what?

[@trackpadgod]

they dont matter@@ParkusYT

[@justinliu4715]

Instead of leds could one replace them with motors ? ( specifically small dc air pumps)

[@Science.Buddies]

Yes, you could map the joystick inputs to any other output that you want. Please check out our Arduino tutorial playlist linked in the description, we have videos about motors and pumps as well!

[@cocomokotoko6706]

i heve an other jojstik

[@jeshuaarias2281]

can u add a link to the code you used in the video.

[@Science.Buddies]

We don't have this exact code available, but here's a project with example code that uses a joystick: www.sciencebuddies.org/stem-activities/drone-arduino-steering-joystick

[@Outer-Heaven_Supercomputer]

arduino website has sample codes, you may find one that fits your project there

[@drawingboy5271]

Also Love your videos too

[@rBlueBoi]

awesome

[@monershokry8406]

HELL ITIS VERY GOOD I LOOK FOR SAME THIS befor but the calibration propleme i need to delet this item how i can do it ?

[@johngram3302]

Where is a good place to get parts for this project?

[@Science.Buddies]

Please see the links in the video description.

[@zaydensus7981]

Can you help me ??? There is a pin that says SW help plz

[@Science.Buddies]

That might stand for Switch - some joysticks are "clickable" meaning you can push down and it will also act like a button.

[@JustARandomDude-xq9zn]

I opened the serial monitor and nothing displays

[@deadhorseproductions2477]

same thing. you figure out why?

[@Fiski3434]

Did you add in the serial.print code at the bottom?

[@drawingboy5271]

Can you please give the code for the led joystick thing

[@Science.Buddies]

// joystick pins const int LRpin = A0; const int UDpin = A1; // variables for analog readings int LR; int UD; // neutral readings for calibration int LR_neutral; int UD_neutral; // red, yellow, green, blue LED pins const int Rpin = 11; const int Ypin = 10; const int Gpin = 6; const int Bpin = 9; // LED brightnesses int R; int Y; int G; int B; const int deadzone=10; void setup() { // put your setup code here, to run once: // Initialize serial communication Serial.begin(9600); // get neutral readings for calibration // make sure you are not touching the joystick when // the program starts!
