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?
My homework for lesson 35. th-cam.com/video/2RBpyZ0GkdM/w-d-xo.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)
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?
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°?
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.
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?
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
Homework submitted th-cam.com/video/aoL7jmaUhrQ/w-d-xo.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.
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.

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
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.: th-cam.com/video/VnmLOB5zxcY/w-d-xo.html
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.
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 am from Vietnam and I have watched from the first videos on this topic
Welcome!
Thanks Paul! I always enjoy th math component of the lesson, makes the code very portable...

Excellent!
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!

Another Great video by @PaulMcWhorter.
Servo is not fidget toy! 😂😂😂
Thank you sir, another amazing lesson.
I would have you on my team, 100%
Hi Paul. I would like to control a servo via an nrf24L01 trans receiver. Do you have a video for programing the nrf24L01?
you have the gift!

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?
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.
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
Nice explanation for controlling a servo without using a library. I take it silly dog videos are ok? : - ))
Guys the new raspberry pi 5 just got released

ESP32 board is very important and very useful than Arduino and Pico
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
