PID Control with Photocells

Introduction

A proportional-integral-derivative (PID) controller is a feedback loop that continuously calculates an error value e(t) as the difference between a desired setpoint (SP) and a measured process variable (PV) and applies a correction based on proportional, integral, and derivative terms. In this study, a photocell will be used to test the ambient light and apply the feedback loop to a code.
