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.

What does PWM stand for and how is it related to digital pins on an Arduino?

Explain the concept of duty cycle in PWM and its significance.

How does a duty cycle of 25% affect the voltage supplied to a component?

What is the range of values used to represent the duty cycle in PWM on Arduino?

Describe the difference between using digitalWrite and analogWrite in the context of PWM.
