Please go through the code and guide. Your program never reacts properly to input changes because: Wrong addresses and initial values fed to PID Calling the same instances of PID ,2 times that may overwrite Revert wrong initial values to meaningful values I made a lot of changes to make it functional I hope it helps, hdhosseini
