What is pmw?

PMW stands for Pulse-Width Modulation and is a technique used to control the amount of power delivered to a load such as a motor or LED. It involves the use of a pulse wave signal with a varying duty cycle. The duty cycle refers to the amount of time that the signal is ON or OFF within a given period. By varying the duty cycle, the average power delivered to the load can be controlled. This technique is widely used in electronic systems, from controlling the speed of motors in drones and robots to dimming lights and controlling the brightness of displays. PMW is a common feature in microcontrollers and can be implemented using software or hardware.
