PID control card


i'm new to the arduino.. and programming in general. i just recently purchased my first arduino UNO :)

a project thats interests me alot is PID calculations and want to build something to play around with this. i was wondering if anyone has built anything similar to this? a PID card with 3 potentiometers for tunning each parameter gain on the fly.

inputs would be: -(0 to 5V) analog input -(0 to 5V) analog input for PID calculation - pot. for P_parameter - pot. for I_parameter - pot. for D_parameter

output: - (0 to 100%) PWM



there was a guy that made a library for pid control

im not too familiar with it, but perhaps it can help you.

A PID controller would be a good idea to build regardless someone did it a thousand times or not ;) One more thing, besides the three nobs, you need a reset button to reset the integral :)
