Hello. I am trying to set up a system of Servomotor and a combo board (gyro + accelerometers). I am using PID and the setups is such: setpoint is zero degrees, input is angle from the combo board and output is Amplitude of rotation of servo arm on my servo. I made it work, but it only works when inc…

PID does not sense negative values.

I did not want getting any negative amplitudes. I was expecting it to increase amplitude when angle is not zero.
