555 Timer as a PWM Generator

Overview

This experiment demonstrates how to use a 555 timer IC to generate Pulse Width Modulation (PWM) signals, often used for motor control and dimming applications.

Components Required

• 555 Timer IC
• Resistors
• Capacitors
• Power supply
• Breadboard and wires

Procedure

1. Configure the 555 timer in astable mode to generate PWM output.

2. Adjust the timing components to control the pulse width and frequency.

Expected Result

The 555 timer will produce a PWM signal, with varying duty cycle depending on the resistor and capacitor values used.
