Question

What is pwm

Accepted Answer

PWM stands for Pulse Width Modulation. It is a technique used to control the amount of power delivered to a load.

PWM involves rapidly switching a signal on and off to control the average voltage or current delivered to a load.
It is commonly used in motor control, LED dimming, and power regulation.
The duty cycle of the signal determines the amount of power delivered to the load.
Higher duty cycle means more power delivered, while lower duty cycle means less power delivered.
PWM can be implemented using hardware or software.
It is an efficient way to control power as it reduces power loss and heat dissipation.
PWM frequency and duty cycle can be adjusted to achieve the desired output.
Examples of PWM controllers include the Arduino PWM pins and the 555 timer IC.
