Capacitive Bluetooth Digital Ceiling Fan Controller via Android

The various operations involved within the circuit can be understood with the help of the following points:

When we send ASCII characters from the BT android app via the Bluetooth module(HC05), the PIC microncontroller will interprete it through the program written on the microcontroller and thereby regulate the speed of the fan.

From the circuit simulation, the virtual terminal represents the Bluetooth module, while the LEDs are for the status of the fan speed.

Three NPN transistors (bc337) and three 6v relays are used for the control of different fan speed of the fan, but a 12v relay can also be used.

The program is written in Mikroc.
