About This Class

4b1e9e8b

In this project, we will build on our previous CPU fan project - Part 1 and will learn how to use the Arduino to control a CPU fan with a button. By pressing the button we will be able to cycle through three speeds of the fan (low, medium and high).

We will understand how you can use buttons to control electronic components and you will also be introduced to the built-in internal pullup resistors in Arduino and get familiar with how they work and how they can be applied.

Learning Objectives:

  • Using a button to control our fan
  • Understanding an internal pullup resistor via INPUT_PULLUP on the Arduino
