In this class we will be using the Sunfounder Raspberry Pi Pico W Keppler Kit. It will make things a lot easier if we are working on identical hardware. the link below is to amazon, and is for the identical hardware I will be using in this entire class.

In this video, I will show you how to control a servo using the Raspberry Pi Pico W. I show how the servo position is controlled by the pulsewidth of a pulse sent to the control lead of the servo. Enjoy!

Paul, over the years you have given us countless enjoyable hours of interesting, useful, and challenging projects. Heart-felt thanks.
Thanks! Appreciate having on the channel.
Thanks Paul! I always enjoy th math component of the lesson, makes the code very portable...
Thanks Paul, I am from Vietnam and I have watched from the first videos on this topic
Welcome!
One thing I havent seen addressed in any pico servo video Ive watch is dealing with the servo voltage when they are run at the correct voltage. The pico is 3 volts . Servos to include the one you are using should be run at 5 volts to get the best speed / torque. This would require running the servo at 5 volts and the pico at 3. So does something has to be done signal voltage?
Projects are flowing much more consistent with since I've been learning from doing and watching your current and past streams
I wish you get into ROS1 noetic its still a powerful pkg combining server running operation.. ROS2 I'ma wait a little on that, Ros 1 makes a lot of
sense without repetitive command structure to mimnic and already sweat operation.
Welcome back!
Warning! Warning! Will Robinson... The Raspberry PI-5 is finally coming out! 🥰 More stuff to learn. 😎 Thank you Paul for the Servo example.
This is a very informative and UNDERSTANDABLE VIDEO! THANK YOU PAUL!
Thanks Paul. I was able to find your mistakes before I wrote them down in my notes, but I still made one before i ran my code. A could not have done that a year ago! I love the math, I cant do it without my notes and you telling me when I need to use it.
Excellent!
I would have you on my team, 100%
Servo is not fidget toy! 😂😂😂
Thank you sir, another amazing lesson.
you have the gift!
Another Great video by @PaulMcWhorter.
Here is my Homework solution Link: ruclips.net/video/WSLRbilrPH8/видео.html Can't wait until the Trigonometry classes. 😃
LEGEND!
Paul, why do we use 0.5 ms for a 0° angle and 2.5ms for a 180° angle, if the datasheet for the Micro servo SG90 specifies 1 ms for 0° and 2 ms for 180°?
Nice explanation for controlling a servo without using a library. I take it silly dog videos are ok? : - ))
My homework for lesson 35. ruclips.net/video/2RBpyZ0GkdM/видео.html I have been binging several astrophotography channels. I think the McWhorter following would appreciate this hobby. A lot of moving parts that need to work together. I digress. One of the presenters mentioned "silly cat videos" before ending the video. I had to smile. (Sorry I posted this on lesson 35 by mistake)
Thank you Paul!
Great time good info.
my servo seemed to run in reverse: assuming 90degrees is straight up...0 degrees being fully clockwise (on the right) and 180 being fully counterclkws (to the left.) ?How to reverse the motion? well I used the absolute value after subtracting the max & min values.
revrsVal = abs((writeVal-8191-1638))
servo.duty_u16(revrsVal)
Now 0degrees = fully counterclockwise, 90degrees = straight up and 180degrees = fully clockwise
Hello sir. I had posted this question yesterday in the comments section of lesson 29 of your jetson nano series. I thought you might miss it, so I'm posting it here again. I feel awful about posting it in wrong place but I'm strugging to find a solution.
My project will have an x-y gantry for which I need to use stepper motors instead of servo motors. What gear and python libraries will I need to use stepper motors with the Jetson nano?
Mavelous
Paul, how do you "calibrate" the servo to actually move between 0 and 180 degrees. Your servo overshot most of the angles. Would you have to customize the code for each individual servo?
Just adjust the math. Find the write pwm value that puts the servo exactly at 180 then use that value in your equations of the line.
HI Paul, I am a grade 9 student and currently working with Arduino, I am very interested in robotics, electronics, and physics, (things like motors, engines, and moving stuff). I am currently following your Arduino tutorial (not raspberry pi). Is there anything you would recommend for me to use? Like a new type of Arduino that is more focused on robotics, or anything else that would suit my needs?
Also, I have really liked your Arduino videos, easy to understand.
Thank you.
Start by going through all the arduino lessons, then do the Pico Pi lessons.
@@paulmcwhorter Thanks, is there a set I need to buy online?
Guys the new raspberry pi 5 just got released
Has anyone else have the issue of ads getting longer. No problem with 1 second ones but later there are 2 ads with a lenght of 5 mins. One is stupid game and the other is for a security camera.
Homework submitted ruclips.net/video/aoL7jmaUhrQ/видео.html
I do the actual assigned homework and some extra credit. Sorry it's so long but I think is has some good info.
Thanks Paul for all you do.
Great video, thanks for sharing.
Hi sir I need some help I have Arduino pro mini I need to read code from Arduino pro mini in Arduino software I need to know how it's work can you please help me
What's a figet?? Long after my time.
Wow, Fidget is a very old word, even going back to my childhood. To fidget means to sort of release nervous energy by performing useless movements. The dictionary defines it as: Fidgeting is the act of moving about restlessly in a way that is not essential to ongoing tasks or events. Fidgeting may involve playing with one's fingers, hair, or personal objects. In this sense, it may be considered twiddling or fiddling.
When I was growing up, fidgeting was viewed as a bad thing, or annoying behavior. Children were encouraged not to fidget. Nowdays, they try to give kids non-annoying ways to fidget, so they make fidget toys to allow release of the nervous energy in a harmless way.
Redid the assignment per instructor suggestion so that the servo direction of rotation matches the potentiometer direction. ruclips.net/video/OU6QtEfFPS8/видео.html

Thanks, Paul
LEGEND!
Getting caught up on lessons. Here is my HW: ruclips.net/video/XuN6y1kvn-o/видео.html. Thanks for the great lessons Paul!
LEGEND!
Thanks so much, Paul, for this awesome content! Here is my solution to your homework assignment. I was able to calibrate the servo using math, as you suggested in the comments.:

LEGEND!
ESP32 board is very important and very useful than Arduino and Pico
Thanks for another great lesson Paul, my homework for lesson 36: ruclips.net/video/tCtxIg1BVz8/видео.html
LEGEND!
My servo is not a fig-it toy.
EXACTLY!
My servo is not my fidget toy
EXACTLY!
my fidget toy is not a servo!
EXACTLY!
Hi Paul. I think it is better to produce IOT with ESP32 course than this useless Pico course
