PWMPins

PWMPins refers to the specific pins on a microcontroller or development board that are capable of generating Pulse Width Modulation (PWM) signals. PWM is a technique used to control the average voltage supplied to a device by rapidly switching a digital signal on and off. The width of the "on" pulse relative to the total period of the signal determines the average voltage.

These PWM-capable pins are essential for a variety of applications. They are commonly used to control the brightness of LEDs, the speed of DC motors, and the position of servo motors. By adjusting the duty cycle, which is the ratio of the pulse's "on" time to the total period, users can achieve granular control over these outputs.

Microcontrollers from various manufacturers, such as Arduino, ESP32, and Raspberry Pi Pico, all feature dedicated pins for PWM output. The number of available PWM pins and their specific capabilities can vary between different models. Software libraries and functions are typically provided to easily configure and control these pins, allowing developers to generate PWM signals with desired frequencies and duty cycles without needing complex external circuitry. Understanding which pins are PWM-capable is a fundamental step when designing projects involving analog-like control of digital outputs.
