I have successfully controlled an analog 360 degree servo using a slide potentiometer, with the pot sending a 1000ms signal at one end of the pot and 2000 ms at the other. This gives me nice and smooth rotation speed control all along the pot axis.
I recently got hold of TowerPro MG90D servos, which would be ideal for the app I have in mind because of size and power, but I do not seem to find the right signal to send. If I run the same code, I get the servo turning 100% clockwise first, then in the middle a jittery very small step movement, then at some point full speed counterclockwise.
So my question is, what is the signal I should be sending to the digital servo?
This servo is indeed a 360° servo. Please see https://youtu.be/pyGhbPLZA04
Many thanks in advance!
