H Bridge Motor Controller Circuit

Motor control is the core of automation & robotics. Without locomotion or any movement, a robot is dull and lifeless. The H-bridge Motor Controller is a true concept for DC motor control

It gives you rotary control of the motor: move motors forward, backward and with varying speeds. In this project, we are going to design an H-Bridge Motor Controller/Driver Circuit
