Hi, I'm working on a project using 2 x DC Motors with encoders and need to setup closed loop PID control. The Arduino Uno has 2 x interrupt pins (pin 2 & pin 3) which I need for each of the encoders to make the PID control code work as needed. I'm using this shield: Arduino Motor Shield
The problem is that this shield uses pin 3 for the motor pwm.
Does anyone know if there is a way to use this shield and control two motors with encoders using PID?
