PID control can easily be done in the arduino controller.
We will be using an immersion heater in a cup of water to keep the temperature at a constant value. Our immersion heater will be controlled through a relay using time proportional control from our PID output. A J type thermocouple will be used with the P1-04THM thermocouple temperature and voltage input module. The Arduino PID Library by Brett Beauregard will be used with our productivity open P1AM industrial arduino. Our program sketch will use productivity blocks, that will then be verified into the C++ code in the Arduino IDE. Let's get started.

A Proportional-Integral-Derivative algorithm is a generic Control Loop feedback formula widely used in industrial control systems. A PID algorithm attempts to correct the error between a measured process variable and the desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly and rapidly, to keep the Error to a minimum.
