Working with Atmel AVR Microcontroller Basic Pulse Width Modulation (PWM)

Avr Pwm 01

Pulse Width Modulation (PWM) is a technique widely used in modern switching circuit to control the amount of power given to the electrical device.  This method simply switches ON and OFF the power supplied to the electrical device rapidly. The average amount of energy received by the electrical device is corresponding to the ON and OFF period (duty cycle); therefore by varying the ON period i.e. longer or shorter, we could easily control the amount of energy received by the electrical device. The Light Emitting Diode (LED) will respond to this pulse by dimming or brighten its light while the electrical motor will respond to this pulse by turning its rotor slow or fast.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. now after years of remembering good old Roy G. Biv ,you came up with a way to use 5000 years of technology to replace him.
