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

PWM generation using a 555 timer IC: A triangular waveform (green) is compared with a control voltage (blue pulses) to generate a Pulse Width Modulated (PWM) signal. As the control voltage varies, the pulse width changes accordingly. The 555 timer operates in comparator mode, with components R1, R2, and C1 shaping the triangular waveform. This setup is commonly used in motor speed control, LED dimming, and signal modulation applications. #ne555 #pwm #circuitdesign #electronics #CircuitSimulation
