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
