# Fan Module
## Introduction  
<font style="color:rgb(0,0,0);">The fan module uses a DC motor to convert electrical energy into mechanical energy, driving the fan blades to rotate. This module can be used to design smart fans, heat dissipation systems, propellers, and other similar applications.  </font>

<font style="color:rgb(0,0,0);">The fan module can be connected to the micro:bit smart hub's interfaces: P0, P1, P2, P8, P12, and P16.  </font>

> **Note:** Avoid physical contact with the fan blades during operation to prevent mechanical injury.

<font style="color:rgba(0, 0, 0, 0.85);">In the MakeCode coding software, by adding the </font><font style="color:rgb(0,0,0);">micro:bit</font><font style="color:rgba(0, 0, 0, 0.85);"> extension, you can program the fan module to start or stop. By using the "plus" block, you can adjust the fan's speed.  </font>
