Great stuff

hi, very helpful. thank you

Hah, I came across your video because I'm building exactly the kind fixture you're using. I also noticed the disparities of "economy" servos and needed a way to "calibrate" them. I'm using a pair of limit switches with a configurable angle between them. The pico increments the duty in one direction until it hits the first switch and records the duty at that position. Then it does the same thing in the other direction. Finally, knowing the angle between switchs and the duty range between them, I can find the duty per degree. The limit switches are probably overkill, but its more of an excuse to learn how to use them for a future project.

Interesting to see those little servo devices. I have been implementing servo control on lifting equipment for much of my working life. Those little servos look like fun to play with. I am surprised they use 50hz. Thanks regards Chris

Do you have a video explaining how to use continuous servos

How would I go about changing the speed of the servo and have it programmed to buttons so 1 button makes the speed go down and another button makes the speed go up? Is this possible? If so I would also like to do the same with the amount of rotation the servo can move and have that also programmed to 2 buttons. I’m a complete beginner to this stuff, I have managed to get my servo moving from the push of a button but now I want to implement the above mentioned functions, just can’t wrap my head around how I would code it. Any help would be much appreciated!

Great tutorial! How would you control a bigger servo (e.g. MG996R) ? Would you need something in between Pico and MG996R ? Or MG996R can directly be connected to Pico?

It is a little far from your excellent points, but - where did you find those neat vise clamps?

or it could move a glass marble over a threshold, letting it run down a track ...
