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.
