PWM (Pulse Width Modulation) is a technique to control power delivery by varying the width (duration) of a digital pulse. It’s commonly used for motor speed control, LED dimming, and voltage regulation. By adjusting the duty cycle (ratio of ON time to total cycle time), you can effectively control the average voltage or power delivered to a device. #ElectronicsEducation #electronicsrd #electronics | Electronics Education

This simulation shows a PWM (Pulse Width Modulation) generator using the 555 timer IC. The configuration operates in astable mode, where resistors and a capacitor (R1, R2, and C1) determine the charging and discharging cycle of the capacitor, producing a triangular waveform at the capacitor and a corresponding square wave at the output. By applying a varying DC control voltage at the control pin (pin 5), the threshold and trigger levels of the 555 are shifted, which changes the duty cycle of the
