How to Use a Potentiometer with Arduino analogRead

This video tutorial explains how to use a potentiometer with Arduino to control an LED's brightness. It covers the basics of potentiometers, building a circuit in Tinkercad, and using the Arduino IDE to read analog values. A programming challenge is presented to control LED brightness using the potentiometer. The tutorial also introduces the Arduino map function for converting values between different ranges.

Explain how to convert the ADC reading from 0-1023 to a voltage range of 0-5 volts.
