Introduction
In this tutorial, I will show you how to connect some motors to your Raspberry Pi4. DC Motor with Raspberry Pi lies with the Motor Driver.
What is motor Driver: A Motor Driver is a special circuit or IC that provides the necessary power (or rather the current) to the motor for smooth and safe operation.
we should never connect a motor directly to Raspberry Pi
