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

Electric motor speed controller. In this video we learn how to design a simple PWM speed controller for a DC motor learning how current flows in the circuit and what each component does. You can even build the circuit yourself! #engineer #engineering #electrical #electronics #engineeringmindset | The Engineering Mindset
