Arduino for Beginners - 2022 Complete Course - Activity 04 - Solution

This tutorial explains how to control the brightness of an LED using a potentiometer on an Arduino. It covers setting up the pins, reading analog values, scaling them, and writing to the LED using PWM. The video also demonstrates compiling the code and testing the setup, showing how the LED brightness changes with the potentiometer's position.

What is the range of values returned by the analog read function?

How is the brightness of the LED calculated from the potentiometer value?

What is the difference between analog read and analog write functions?
