A PID controller is a widely used industrial control feedback mechanism. The controller attempts to correct the error between a measured process variable and a desired set point through the process of first calculating the error between the two values and then producing a corrective action that can adjust the process consequently. PID controllers have been used for various applications and available in the market although mostly present in other countries. DC motor PID controllers could roughly cost at around Php 8,250.00 - 10,500.00 per unit. The commercial PID controllers propose the most advanced attributes that would cater to any of its capable applications, though the complexity of the PID controllers in the market would be unreasonable a module for people who need to understand PID controllers such as students and enthusiasts. The goal of this study is to implement the PID controller using a microcontroller to control a low power DC motor. The target angular velocity specified through the input module must be accurately obtained.
