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.

What is the primary focus of the video regarding fan types?

• PWM compatible fans

• Three-wire fans

• Four-wire fans

• Two-wire brushless DC fans

What should you check before purchasing a fan for Arduino projects?

• The fan's color

• The fan's size

• The fan's specifications

• The fan's brand

Why is a transistor used in the fan control circuit?

• To act as a control valve for current

• To replace the Arduino pins

• To increase the voltage

• To decrease the current

What is the role of the gate pin in a MOSFET?

• It acts as the control pin

• It connects to the fan directly

• It connects to the ground

• It connects to the power source

Which Arduino command is used for reading the button state?

• analogRead

• digitalWrite

• digitalRead

• analogWrite

What is a potential application of controlling a fan with a sensor?
