Learn MicroPython #6 - fade an LED with PWM

In this video we will discuss a technique used in the digital world to deliver varying power to a device without requiring an analog (varying) voltage. The technique is called pulse width modulation (abbreviated PWM) and works by controlling the duty cycle of a square wave, which is the ratio of the average on-time to the total time. For example, a 50% duty cycle would indicate a signal that is delivering power 50% of the time. PWM is used in so many places. It can fade LEDs, spin motors, or even communicate analog data using only digital GPIO pins. We have entire playlists on learning open source software so have fun learning!
