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:

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:

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 .

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!

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

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

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 :)

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!

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

YouTube 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.

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! :)

Tell Bosco to keep doing good work protecting one of YouTubes 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.

[Rorschachcollision]

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

[sravanimalekar]

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.

[kenspyder]

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!

[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

[urosurgery]

thanks for that super-long episode! :-)

[tylermakesstuff]

Bosco. It's 2022, and I'm just finding these videos. I've watched all of them up to this point so far and they are incredible. Thank you so much for sharing your knowledge!

[paulsmigel]

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. 👍👍👍

[DanTran-ifjt]

Bosco!


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

[tomreese]

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

[slnuygn]

BOSCO!!! Someone up high incoming, boom! Down low, boom! Definitely one of the most fun videos in this series to build and code along at home. God bless you!

[unknownswords]

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. !!!!
