H-Bridge Circuit for DC Motor Reversal

Overview

This experiment demonstrates how to control the direction of a DC motor using an H-Bridge circuit.

Components Required

• 4 NPN Transistors (e.g., 2N2222)
• DC Motor
• Resistors
• Power supply
• Switches
• Breadboard and wires

Procedure

1. Connect the four transistors in an H-Bridge configuration with the DC motor at the center.

2. Use switches to control the transistors and reverse the direction of the motor.

Expected Result

The motor will rotate in both directions depending on the transistor switching.
