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 .

Most Arduino forums/social media are recommending Paul McWhorter when beginners ask where they should start. Well done Paul! BOSCO!
TH-cam 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.
Bob I second that motion.
He is a great teacher of the very cool Arduino system!!!!
Totally agree.
what past achievements do you mean?
@@waelal-halawani8056 Watch his other videos and you will discover!
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
Did you ever end up getting you a Arduino set to play around with
In case you don't hear it often enough, you're awesome at this. Thanks for these videos!
Glad you enjoy it!
I flew RC planes in the 80s,found 3 servos in the basement and they still work. Hope Bosco is safe from Corona.
"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
Indigo, Bosco, hey Paul I have completely watched and thoroughly enjoyed all 33 episodes so far, todays episode was by far the greatest fun yet, really enjoy your enthusiasm. Thank you so much for taking the time to produce these videos.
I love how watching the previous lessons really starts to pay off in these lessons. Very easy and logical if you follow along.
This project was so much fun.
Keep that great work coming Paul. Cant wait for all the new things to learn with you.
Bosco!
Bosco!
"because we do math" lol :)) This episode is so much fun.
Bosco , I really much appreciate your Tutorials , keep watching them one by one and rewrites the script by my own and getting the same results as your,s , much thanks to you Paul .
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! :)
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. 👍👍👍
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! :)
So I binge these and didn't have time to wait to get these in, so instead I assumed I knew what you were going to do and used the blue one with the kit to make a 0-170 degree turn lazer pointer (I still ordered the hi-tec ones for future projects) but I'm getting this down! You're an awesome teacher for me to be able to do all this by myself with 0 help. I'm picking it all up and am very happy. I finally feel like I've found a career worth going 100% with.
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.
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!
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.
“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
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.
I live in Venezuela so ordering an extra servo would have taken a while so instead of controlling two servos with the joystick I ended up controlling the servo from the starter kit with the xValue and then the tone of the passive buzzer with the yValue. It would have been fun to use two servos but for now it was great practice! I have really learned a lot and I am eager to continue with this most excellent series of tutorials
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.
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.
Bosco! Another thoroughly enjoyable, educational, life improving tutorial from one of the best teachers out there. Thanks Paul. God bless!
My pleasure!
There's only one word to describe how good this project was: Bosco!
This was a very enjoyable and challenging project to work through. The quality of Paul's teaching is reflected in the fact that I was able to work through both the circuit building and the code, and get everything functioning correctly, before watching Paul build his circuit and do his coding! And I even understood what I was doing and why! (Well, 95% of it.) A week ago that would have been out of the question!
Thank you, Paul, for providing such a fabulous teaching/learning resource.
Bosco, Paul. The way you teach is very relaxing and the further we get the more interested I become. If I had to learn this from a book like Arduino for dummies, I probably would have quit already. I have printed out all the programs we have already written, where I have added many notes, so as not to forget the instructions and to make them easier for myself. I'm getting to where I wanted to be. It won't get any easier, but I understand everything now. Keep it up.
Bosco!
Made it to the end.
Amazing tutorials, really amazing.✌
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.
"Battle of the Servos" lol. I love your videos Paul! and... Bosco!
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.
Bosco. Another great tutorial. My kids and I wanted to build a robotic arm and control it via joysticks. I could have just downloaded some code and made it work, but I thought it would be better if I learned how to do it myself. Your videos have helped me along the path to that goal. Thank you.
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.
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@
In South Africa they sell it as Prestik.🤓
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);
}
}
Bosco! You 're great teacher Paul .. you really make arduino so much fun especially when you make math really work .. your way of teaching exactly what the doctor ordered . Baaaam! thank you very much I really appreciated
Awesome tutorial Paul! One thing I’d like to mention is that if you would like to get a number between 0 and 180, arduino’s IDE does have a built in command to help with that, map(). Its syntax is map(value, fromLow, fromHigh, toLow, toHigh). This can be a useful time saver that can let the computer do some of the work for you. Love your work, have a great day
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 :)
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!
Tell Bosco to keep doing good work protecting one of TH-cams 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.
Hi Paul - It's me again! Bosco still rocks! It WAS a lot to cover - although, you've already covered all the subjects in earlier lessons. It is great to put everything together into one refresher!
And GOD BLESS THE QUEEN!
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!
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!
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!
Another excellent video. Nice picture of Boscow (I hope I have spelt his name right). I have followed every single video and have worked on every homework exercise. I am LOVING this course!
Bosco, Really enjoying these tutorials.
Thanks, I'm hooked.
Bosco!
Paul, you are a true legend in keeping all of us watching till the end of your videos!
Thank you!
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 :)
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.
Bosco! This was a really interesting lesson for me and my mind is exploding with multuple use cases for this project! Thank you for making this lesson easy for me to understand.😊😊
This instructional series is just amaizing! Thank you soo much Paul!
Bosco . Thanks Paul as an Australian Retired Electronics Engineer it is easy but fun and that is the main thing. Really appreciate it.
Great video. By using the code from your other videos I was able to do alot of this coding on my own. I'm really enjoying the tutorials. Hi Bosco!!
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.
Great job!
Thanks Paul for teaching us how to use the Arduino. We see the entire video as the prove, it was nice to meet Bosco.
"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!
Great to hear!
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!
As we move along in the lessons I am having more and more fun. This was a lesson I was looking forward to. Thank you.
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
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.
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)
Basko and thanks! These projects are getting more and more exciting.
Bosco. Enjoy the lessons; I haven't had occasion to use y=mx+b for more than 50 years. Thanks for the refresher.
Watched this great video several times over the years, just superb. Thank you Paul and regards to ‘Bosco’.
Bosco. I have to agree with what everyone is saying. You are really helping me learn how to code with arduino c++. Without you I would be hopelessly lost.
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
Fantastic!
Bosco, Loving these tutorials. I've made it this far in just under a week.
Bosco!!!!
Feeling amazed by seeing glimpse of the power of Arduino!!!
🤩🤩
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.
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.
Hi Paul
Yes I watched your lesson 33 to the end, Where you explained the different temperatures and about Bosco.
Thankyou
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!
Wow, thank you!
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.
I certainly did get to the end. Really enjoying the videos. I hope Bosco is not too busy in his official capacity
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!
Bosco! I did the project on my own. Really enjoy following your guidance and finish the homework. Thank you very much.
Fantastic!
"You don't wanna mess with BOSCO"
Enjoying each and every video of this series. I hope to learn new things and be able to convey them like you do.
Much Love.
You can do it!
Bosco! I'm very glad that I did it without watching or copying the contents in the lesson. Thank you so much Paul!
Glad it was helpful!
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.
Bosco! Awesome job Paul, I've watched your videos from the beginning, I wanted to collab with you sometimes and build stuff.
Don't listen to those people who doesn't like putting Math in their designs, I think it's awesome!
Bosco. A really enjoyable lesson Paul. I like the way you don't edit out the code gaffs as watching you fix them is instructive.
Glad to help
Bosco
Thank you for sharing your videos. I am enjoying learning from them.
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!
BOSCO!
your videos sir Paul are really a big help in our Thesis.
continue sharing knowledge! THANK YOU!
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!
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.
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. !!!!
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
Bosco, made it to the end great lesson one thing I noticed on mine I'm either picking up noise. On my switch cause I had intermittent 0 with out a button press so I used a pull up resistor. Work perfectly after that thanks again for these lessons.
I hope Bosco is staying warm! Thanks again, this was a fun project and showed a practical (if unlikely) way to use what you are teaching me. Haha Death Ray indeed! Pookie is the Duct Tape of the engineering (and radio) world? Thank you so much for another fun lesson.
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.😶🌫📚💡
bosco!!! amazing video brother. have struggled along with the math although the repetition has seen it finally sink in :) thank you so much for another great video
Great to hear!
Must have changed the secret word with the new videos. It is now Indigo. Great job Paul. I am thoroughly enjoying these videos and wanted to let you know I do use the math :) Your explanations of what is going on are great. I usually do the projects myself and then watch you do them. Thanks again.
Glad you like them!
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!
Bosco!
Bosco!
you are amazing at these videos and keep it up I'm only 15 and these tutorials are the best for people like me bc I like this kind of stuff.
so continue what you're doing and I will watch till the end of the tutorials with pleasure.
Personally, I'm glad you do the math. Math was always one of my best subjects in school, but after freshman year of college I didn't really encounter much that was more complicated than basic addition, subtraction, multiplication, and division, despite my heavy STEM focus, and I'm afraid my skills have gotten a bit rusty. It's nice to have a bit of a refresher.
I was able to complete this one on my own! Yeah! Many thanks to Paul and Bosco.
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.
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!
Wonderful mix of wisdom, tinkering and improvisation, Paul is really enjoying himself ! That is very infectious. An excellent series of tutorials, I only came to have a quick look and now I am completing each lesson reasonably (!) successfully. Great fun, learning lots, thanks Paul.
(PS...is there a better method of connecting wires to the breadboard, it seems a bit hit and miss? Maybe I should use more substantial wire and cut each connection to length as required, this might improve the mechanical strength/integrity of the connections?)
Mr McWhorter, I recently got a Raspberry Pico and can definitely say, its a bleak learning landscape without your tutorials! :)
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....
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.
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!!
Bosch - made it through to the end.
Buscov looks like a very polite man, thank you for the tutorial Paul really appreciate it :)
Made it to the end, Paul! Hay there, Bosco from New Zealand.
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
