    Good Morning All,

    I have the Omni-wheel Vector robot and I am working on making it autonomous. I used the wheel speed in m/s to get a PID output. My question is how do I convert the PID output to a PWM for my Analogwrite command? My PWM range is -225, 255.



    The analogWrite() command takes values from 0 to 255. You need to take the absolute value (or magnitude) of your pid output, scale it to 0-255, and set the direction pin output for that motor high or low depending on the sign.
