In this lesson we learn how to incorporate a Joystick into your arduino project. We show how to connect the joystick and how to program it. A joystick can be thought of as two potentiometers which can work together to control a variety of devices. The joystick also has a simple on off switch.
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 .

"Indigo" i will watch your all arduino lessons as long as you make
AMEN! They are amazing!
indigo please protect this good man, he is producing some of the best future engineers in the world
We are using your tutorials for our Computing lessons (High school ENGLAND) and are really enjoying them so far. We have watched up to lesson 32. BTW INDIGO!!! Thank you Paul McWhorter! From Emmy. Year 8 England.
EXCELLENT! Keep going, and then when you are done with these lessons think about taking the Raspberry Pi Pico W classes. Keep learning, and you will go far! Well done. Tell your classmates hello for me.

I didn't take that subtle hint from the last video to invest in more servos as seriously as it is now clear that I should have! I've got a couple more on the way. What I did do was hook up a red and yellow LED (never green, that's for special occasions!) and brighten and dim them along the X and Y axes. Then I got the idea to hook up an RGB LED to play with blending red and green similarly. I thought about connecting the blue line up to the switch but haven't spent the mental capital to figure out how to handle the pull up resistor function yet.
"Indigo" - Engineer here. I got my dad hooked on Arduino, and he turned me on to your videos. Great stuff!
Indigo !!! Thanks Paul for a great series. I’m a 76 year old retired UK citizen who used to be in IT in yesteryear. I have to confess that the toggle switch logic tested my brain to exhaustion but I think I got there in the end. As a keen aero modeller I’m looking forward to the next servo challenge. Thanks for series Paul.

Indigo is your faithful guard. Always appreciate your guidance.❤
indigo is the bestest boy! So I'm a little late to the party but I've been following along so far. Have to say you are a really good teacher. From getting concepts across to informing on why and what is the cause and effect of each aspect of the different components. Thank you for all these videos on so many different systems. And still putting out new content. I have a friend who got your kit and showed it to me. I had mine ordered the next paycheck, lol. So we've been taking this class together. Been a long time since I've actually put some effort into learning something new. So again thank you, so, so much!! keep up the great work in all you're into! Cheers!
This was a good opportunity to build my first wiring harness. I cut the indigo wire a little shorter than the others but it all worked out.
Hi Paul, Love the video, I am 80 years young/retired attorney. I doing the course using an STM32 emulating the Arduino. FYI STM32 at the pins is 3.3V while Arduino is 5v. This caused a bit of problem w this lesson: was not reading the SwitchPin, and the JoyStick values were wrong and did not recognize the changes in value when i moved the JoyStick. To fix the Switch in pinMode, I need: pinMode (switchPin, INPUT_PULLUP); for the JoyStick to work instead of using 5V input i utilized the STM32's 3.3V. These revisions fixed all. Now I will move on to the Servo. If there are issue I will post.
Working my way through these videos and finding them so useful. The theory is proving so much more understandable than it ever did in class many moons ago. Have to say though Indigo seems an unusual name for a dog.
Thank you so much for these tutorials! I recently got a job programming PLC's and visualizing circuitry and watching you explain how to solve problems has been massively helpful. Hope and Indigo are doing well!
Glad I could help!
Indigo! Always watch to the end. New to your tutorials. Only been watching for a couple of weeks. Trying to go in order. You are a good teacher and make most of the material interesting. The math is tough for me so I struggle through that. Last time I did any math more complicated than balancing the check book was high school algebra 55 years ago. But I plan on sticking with it and then move on to build the robot car in your next series. Thanks for teaching. God bless.
Indigo. Paul is the greatest teacher/ trainer I have come across.
Hello Paul! Your lessons are great! Not only I watch them till the end(secret word:Indigo) but I also do the assignments.
Another great tutorial.
As I always say as I’m pushing the wires into the breadboard “In de go” (sorry about that)
"Indigo" - Great lesson again, Paul. Thanks a lot.
Indigo, Yes I watch these lessons. Being a disabled shut-in I can not work out in my shop anymore. I was a machinist so now my interest has to change to something that can be done inside the house. Automation and it's control is very fascinating and important to the world we now live in. BTW I am drinking a coke not coffee.
Thank you for the lessons. You explain them in a way anyone can understand. Thanks to you I was able to clarify many of the doubts that tormented me for months.
Watching these videos to the end just as loyal as Indigo!
If you use the Serial Plotter instead of the Serial Monitor and your x and y values are getting graphed in blue and red you can rapidly mix them to make a very light indigo.
For some odd reason I keep using the Indigo wire to connect to the servo motor - great tutorial. I'm a software developer who wants to learn about the micro controllers, and I'm loving this series. Keep up the great work!
Indigo! Of course I watch to the end! I will continue watching all the way through this series. So thrilled to be getting into more exciting components!
I could rave about this lesson until I was “blue in the face” (or should I say “Indigo in the face”?)
Thanks Paul!
Indigo... new viewer, I very much enjoy your lessons 👍👍
I couldn't think of a joke.
Indigo.
"BOOM" indigo and "BOOM". Worry not, we're faithful and we always watch till the end. By the way. I'm an African and I live in Africa. Thank you.
Indigo. I have watched the first 32 from start to finish and followed along with everything. I had no Arduino experience prior, but I am learning. I have a hard time knowing how to complete the assignments on my own. I will be picking up the reminder of this series in a couple weeks. Thank you for everything so far and Merry Christmas to you and your family.

INDIGO. Great lectures and enjoying every lesson. Thank you

"Indigo"
*lesson==awesome* and you forgot those important semi colons
😂
Secret word for today was Indigo. I watch all you videos till the end, I like them so much!
Glad you like them!
Indigo! always watch to the end!
I did jump ahead to lesson 34 prior to 32. Completely understand how your using the internal pullup resistor in projects.
I really love your "under the hood" explanations. I wanted to do mechatronics engineering when I was in school, but ended up doing software development instead. I like the software world, but electronics fascinates me a bit more. Thank you for the most excellent master classes here on TH-cam. Also, indigo.
Paul, LOVE the videos. Retired EE after 40 years, working for DoD. My Rat Terriers Cooper and Blue watch the videos with me and barked at Indigo. GREAT series, and as other have said, I wish my college professors had been as down to earth as you are! I do the homework on my own, brings back memories of the old IBM 029 Punch machines and System 360/370 from college. Great to have instant feedback now on the compilation results instead of waiting two hours only to find a typo. This is without a doubt, the best $35.00 I have EVER spent! Thank You!! ---Ace
Indigo! Hi Paul, I'm working through your videos and watch them all right to the end. Fantastic work, thank you Sir
Hahahahaha!!!
Indigo doesn't seem to be stressed!
That's fantastic!!!
I hope it helps you in your precious work in Africa, Paul!
Indigo!! BOOM!! Thanks Mr Paul for the clear, practical and educative tutorials.
Secret word: Indigo. Paul, your Arduino tutorials are the best. I recently discovered these tutorials and am going through all of them. I do the homework assignments and have a lot of fun writing Python code to utilize what I have learned. I'm somewhat proficient in Python and C so the programming is simple to me. I'm very excited about learning to build circuits.
I loved the lesson, always wanted to know how joysticks work. Understood everything really well, and Indigo is a real cute dog. Thank you for this great series!
Watched all the way to the end INDIGO!
I added the spaces for the formatting right from the go.
Hello Paul,
Thank you for this tremendous lesson; I had a lot of fun watching it. Indigo is one of my favourite colours too.
I used to play my playstation using a controller and now I'm learning how its little joystick works, and i have a great teacher who teaches stuff without complicating the topic and is easy to understand and learn.
INDIGO, what an amazing dog. Thanks for these tutorials, you're empowering the next generation of engineers .
Glad you like them!
Hi Paul, I have to congratulate you. Your "new and improved series of tutorials" is the best introduction to programing I found around!!
Even though you prepared this material some years ago, I hope you still reading your student comments.
I believe you teaching of math and coding is the perfect mix, you make sense of those formulas nobody takes the time to explain.
Great job!!
Great to hear!
Enjoyed the Indigo Joystick lesson! Thanks.
Indigo. I'm watching and love your material. I've learned a lot and plan on going through the whole series. Thank you for these.
Indigo!
I have always been curious about the joysticks. Especially, when the one on PS controller goes bad. Now I know the exact working tech behind it, so no more banging the gamepad. Thank you so much :)
Thanks for the lesson. Joysticks made easy! Indigo is the colour of your energy.
As a guy who grew up playing a lot of video games I really enjoyed learning how the joysticks actually work. The analogy to a potentiometer is perfect! Love this series and am very excited to start controlling physical outputs with the joystick. Can't wait for the next time I sit down and learn to control the servo with the joystick
The secret word is indigo
Very cool!
Indigo, got my kit and built it along with the video. Great videos thanks Paul.
INDIGO! This was another cool tutorial. You have joined the pantheon of my favorite tutors along with Bucky Roberts.
Indigo. Re-watching the series while I wait for the wifi stuff to come out in the new R4 wifi series. Great stuff. Looking forward to more. Thanks again.
Indigo! Thanks for taking the time to make these lessons. I've been following them in order as well as attempting all homework assignments.
You can do it!
Indigo. Thanks Paul for all your lessons. Keep your lessons coming.
Love the creativity of using joystick in project! Amazing!
"INDIGO", another great one Paul, Thank you for these wonderful lessons!!
I watch all of your videos to the end then review them. I have all of my lessons printed out to refer to.
Thank you
Another thankyou for your videos. With no experience and your videos, Ive used Arduino to control the direction and speed of a motor. Added push button cruise control. Then added a servo to control steering.
My next step is to figure out how to go from prototype to finished project.
Paul MchWorter , you're really wonderful I love your lessons and your way of teaching is extremely interesting I got lots of benefits , thank u very much I really really appreciated
INDIGO!!!!
Thank you Paul, I am absolutely in love with your lessons.
My pleasure!
Indigo! Loving every minute of each lesson!
Indigo! I've watched every one of your videos from 1 to 32 so far all the way through. I started on Saturday, never touched an Arduino before and I'm having a blast making all of these projects. It looks like I'm almost half way through your video series, I'll let you know when I get to video 68.
Hello, my most excellent tutor. I don't have the servos required for this practice, neither I will buy them for now (I just don't need them for my projects), but I will do it with two LEDs to ground the concept. Thank you Mr. McWorther.
I watch your video over and over again. Thank you.
Yes I saw Indigo. Thank you Paul for taking the time to do these videos!
My pleasure!
"Indigo" is the secret word. I really love your lectures. You are the best teacher.
"Indigo", excellent instruction Paul !
Hi Paul! I wired up te joystick before the lesson started. Wrote the program tested it and it worked. then watch you do it. and changed the switch to HIGH not LOW. then i hooked up the servo and wrote te program to move the servo in X. switched X to Y and did the same thing( copy paste) to move Y. downloaded the program and BOOOOOM!!!. then watched the video till the end, the homework was already done. Great stuff! (Indigo,gogogogo !)
Thanks Paul. I might use the two-servo assignment to control an Indigo Laser.
Thanks Paul, I’ve learned a lot watching your arduino video series so far, you really are a most wonderful teacher. I hope indigo is still doing great!
Many thanks!
Hi Paul, I watch every episode to the end and watch again if I don't understand anything. Good boy Indigo. Your tutorials are a great way to learn. Thank you Paul and Happy New Year
Paul, thank you so much for your most excellent lessons. I am following along and even doing/attempting the homework on my own. I have been doing 2 or 3 lessons each night, and can't wait until after dinner to get to computer and do them. Oh yea, Indigo.
Wonderful!
really happy to learn with teacher like you , easy to understand and no question mark left at the end of each tutorial
"in the go " or indigo hade a nice owner he will never let you down 😂
bi thanks from Africa too.
I dont think there is a single one of us that dont watch your videos to the end Paul! Great stuff consistantly ! indigo all the way!
Another great video! And yes I watched to the end ("indigo"). Thank you for creating this helpful course!
I added 10 spaces before Y & Switch, it made nice columns - easier to read.Pupper is Indigo and looks happy. Jumping on homework now. Just picked up 2 of your servos.
Indigo. Thank you very much. We are also using your excellent Arduino tuitorials in our high school in Israel
Indigo, here you go!
Really love your videos Mr. McWhorter :-)
God bless
Your teaching is fantastic and I am learning so much - rgb(75,0,130)
Kihindi. Three years later and people are still learning. Thank you so much!
Hello professor, you have a beautiful home, I'm sure indigo is the happiest a pup can be. I'm greatly enjoying following your lessons. Please never stop being your wonderful self, as it is much easier to connect with the lessons, given your personable approach and volumes of information. Any naysayers who name you to change to omit the diagrams and may are simply lazy. I've been known to go through a video or two multiple times and skip the extra stuff just to get back to the tiny bit I need to recap on. That's why there's a time bar absolve to scrub through.
Thanks a million!
God Bless!
-J.B.-
P.S. I can't wait to advance into your Raspberry Pi lessons. But, one step at a time. 😊
"indigo". This was the first video I watched from you. I loved it.
I heard indigo for today! Normally watch almost to the very end, stop with a few seconds left as that make it easy to get to the next one. Gaining enough confidence to start over and run
some of the earlier activities. Hardware is here!
I love the videos. I do watch and do the lessons as home work. I'm learning so much. INDIGO!!
Wonderful!
Thanks for the 'most wonderful' tutorials!!! You are an amazing teacher, and I wish other TH-camrs would post such great videos. Really glad there are 36 more vids, and I always watch to the end. These videos are a great opportunity for me to learn Arduino before i learn C#. But i wish the recommended servos came in a GLORIOUS indigo color like the Elegoo ones...
(PS I am NOT carole this is my mom's account)
I watch all your videos to the eNd! you are an inspiration to me anD I can not thank you enouGh for all that you dO for us here on youtube! Thank you Paul and God bless!
Yes , watched video to the end and still enjoy your videos thank you very much.
Indigo - another great tutorial Paul - good fun (when it goes well). Learning heaps and the more practice I get the better I get at it - strange that!!!!
Paul: INDIGOOOOO
Indigo: Mcwortererr
I really enjoy this series. Thanks Paul!
Glad to hear it!
INDIGO!
I watched this whole video, and I will watch the entire tutorial!
Though I'm hoping that when I reach lesson 68 (the last video as of this writing) there would be more, and bigger projects. More please!
Indigo. Till today working of joystick was a mystery for me, now solved. thanks a lot.
I watch all of your videos all the way through. Sometimes twice. INDIGO!
Indigo! It is super fun to try out these tutorials. A big thank you to Paul. 😃
Have fun!
Indigo - Thanks for another great lesson, Paul!
Hey Paul Amazing Lessons. Watching them from begining to end and building all the projects. Currently just finished the INDIGO lesson. The lessons are spot on. The right length and clearly explained. Thank you. I will be going right to the end. (and further).
Fantastic!
INDIGO! I always watch the complete video. When I teach, I always make sure to give a piece of crucial information at the end of class to avoid any sneaking out! This was another great lesson! I'm building a teaching program for impoverished and at risk kids (STEM and STEAM based) to get them into engineering and science, hopefully aiming them towards careers in those fields. I was a professional musician for decades and did well for myself. I got into electronics and decided to give back to my community by working with kids. It has been the best gig I even had. I am passing your videos on to my students because the explanations are so good and you use math, which seems to be a lost art with some teachers. Again, you cannot truly create a unique project, going into uncharted realms, without some math skills in your toolbox! Thanks again! By the way, I've been doing your video projects each night when I get home from teaching. They have helped me as well!
Thank you for the comment. Really makes me happy to see others are using these lessons to help people. It has always perplexed me why these free lessons are not used in public schools. Schools will pay hundreds of thousands of dollars for very lame 'STEM' curriculum which teaches nothing, yet I offer these lessons for free and they are not used by schools.
@@paulmcwhorter It seems like the schools want to sell STEM/STEAM programs to parents and students by showing them projects that light up and move and do exciting things. However, it appears that they are afraid to teach anything that requires too much work. I suspect it's a case of "wow, that video is great but having to do that much work might turn students off." Mastery always requires work. Otherwise we would all be masters,, I've given up trying to get into the head's of the people who run these programs. However, my students have to do the work and because I explain why they have to do it, the happily do the work!
INDIGO. Your lessons are great! Greetings from Ukraine, Mr McWhorter and thank you for teaching us!
Excellent lessons, thanks Paul and Indigo!
Glad you like them!
"Indigo" thanks Paul for these great lectures
