AC Fan Speed Control Using Arduino Electronics Engineering Final Year Project

This project includes Bluetooth module (HC-05), which is connected to Arduino digital pins. AC fan controlled by BT136 TRIAC which is connected to Arduino digital pin.

WORKING:

Here we can control AC fan speed using Bluetooth. Bluetooth module can communicate with Android App. Android Application installed in smart mobile which has provision of few buttons. When we press buttons it will send commands to Bluetooth. Based on commands PWM technique performed in Arduino code to regulate AC fan speed. FAN speed information will display on 16X2 LCD display.
