Arduino for Beginners - 2022 Complete Course - How Digital Pins Work with Analog Values (PWM)

The video tutorial explains the concept of Pulse Width Modulation (PWM) on an Arduino Uno. It covers the identification of PWM-capable pins, the definition of PWM and duty cycle, and provides examples of different duty cycles. The tutorial also explains how to calculate the duty cycle using integer values and demonstrates setting PWM using the analog write function on Arduino.
