PWM (Pulse Width Modulation) - Vincent1334/ROS-Humble-BlueRov2-Driver GitHub Wiki

PWM stands for Pulse Width Modulation, a widely used technique in electronics and robotics for controlling various devices. It involves rapidly switching a digital signal on and off at a specific frequency. The ratio of time the signal is on (high) to the total time of one cycle is referred to as the duty cycle.

⚡️ How PWM Works

PWM allows you to simulate an analog signal with a digital output by varying the duty cycle. The higher the duty cycle, the closer the average voltage is to the maximum output voltage, while a lower duty cycle results in a lower average voltage. This characteristic makes PWM an effective method for controlling the speed of motors, the brightness of LEDs, and other applications requiring variable control.
