ON-THE-FLY NOTES
What Is PWM?
A visual explanation of how PWM controls brightness, speed, and output power.
VIDEO NOTE
Video coming soon
This note will include a short practical video explanation.WRITTEN NOTE
PWM controls the average power delivered to a device by switching a digital signal on and off very quickly. Changing the percentage of time the signal stays on changes the duty cycle. A higher duty cycle can make an LED brighter or a motor run faster. In the video, control an LED using PWM, move between several duty-cycle values, and show how the brightness changes even though the output pin is still digital.
