Pulse Width Modulation, or PWM, is a smart way to control power without wasting energy. Instead of reducing voltage directly, the supply is switched fully ON and fully OFF very fast. By changing how long the signal stays ON in each cycle, the average voltage seen by the load changes. This is why PWM is widely used in motor speed control, LED dimming, and power converters. It gives smooth control with high efficiency. In this simulation, the 555 timer is used to generate PWM in a simple and intui
