In this tutorial, I will show you how to connect some motors to your Raspberry Pi4. 

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

Components Required

  1. Raspberry Pi 4 Model B
  2. L298N Motor Driver Module
  3. Lipo Battery 3300mAh
  4. Connecting wires (Jumper Wires)
  5. 5V – 2A Power Supply for Raspberry Pi
  6. 5V DC Motor
