How to Use a DC Cooling Fan with Arduino

This video tutorial explains how to use a two-wire brushless DC fan with an Arduino to create a cooling system. It covers the types and specifications of fans, including PWM compatibility, and demonstrates setting up the circuit using Tinkercad. The tutorial also provides a simple Arduino code for controlling the fan with a button and discusses the use of transistors to manage current. Additional notes highlight the differences between brushless and brushed motors, emphasizing the importance of fan orientation for airflow direction.

Describe how the circuit is set up to control the fan using a button.
