1. Initialization

   Initialize the serial port.

   

2. Main Code

   Loop: the ultrasonic sensor reads the distance values and the serial monitor prints them. It determines whether the value is less than 10cm(this threshold can be modified).

   • Distance < 10, fan rotates.

   • Distance > = 10, fan stops.
