Feb 20, 2026 · Function, Features & Design of the ESP32 PWM Controller The ESP32 is a powerful, low-power system-on-chip (SoC) widely used in embedded systems, IoT devices, and smart automation. The many applications for pulse-width modulation (PWM) include voltage regulation, power-level control, and fan-speed control. Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) [a] or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). Perfect for students, hobbyists, and developers integrating the PWM Motor speed control into their circuits. . The Circuit and How It Works This section explains the design of the circuit and the steps it follows to generate one complete pulse. Pulse width modulation (PWM), also known as pulse-duration modulation (PDM), is a technique for reducing the average power in an alternating current (AC) signal. Design Description This circuit utilizes a triangle wave generator and comparator to generate a 500kHz pulse-width-modulated (PWM) waveform with a duty cycle that is inversely proportional to the input voltage. PWM meaning is effectively chopping off parts of the waveform to reduce the average voltage without affecting the base frequency of the signal. This design also allows the resolution of the circuit to easily be scaled. A PWM circuit for such applications (Figure 1) can be implemented with three op amps from a single quad-op-amp chip. Figure 1 - Logic diagram of the PWM signal generator circuit. The use of op amps allows a wide variety of applications.
