IoT Bluetooth Fan Control

Description

This project uses Bluetooth on the smartphone to control a Smart IoT Fan that comes with an thermal sensor and a bluetooth module. The phone can access the temperature read by the thermal sensor, and send send the command to the phone and adjust the speed of the Fan accordingly.
