Arduino for Beginners - 2022 Complete Course - Set an Analog Value - Change the Brightness of an LED

The video tutorial explains how to modify a circuit to use the analog write function with PWM on an Arduino. It covers changing the pin connection to ensure compatibility, setting up the Arduino IDE, and writing code to control LED brightness using PWM values. The tutorial demonstrates testing different PWM values to observe changes in LED brightness.

What is the purpose of changing the pin number for the LED in the circuit?

How do you change the pin connection for the LED from pin number 12 to pin number 11?

What is the significance of using the analog write function in Arduino?

Explain the difference between using digital write and analog write in Arduino.

What range of values can be provided to the analog write function?

What happens when you send an analog write value of 0 to the LED?

Why is it important to ensure that the pin used for analog write has a PWM function?
