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 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!

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.

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.

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?

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°?

My homework for lesson 35. kzfaq.info/get/bejne/aLhyo9yLla3PlIE.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)

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.

Nice explanation for controlling a servo without using a library. I take it silly dog videos are ok? : - ))

@chapgeo 11 ай бұрын

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?

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.

@paulmcwhorter 11 ай бұрын

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?

@bobvines00 11 ай бұрын

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?

@paulmcwhorter 11 ай бұрын

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.

Redid the assignment per instructor suggestion so that the servo direction of rotation matches the potentiometer direction. kzfaq.info/get/bejne/hbtmhNd2y6y0g2w.html

What's a figet?? Long after my time.

@paulmcwhorter 11 ай бұрын

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.
