The project is designed by using the microcontroller to all the process sequence, A wireless keypad is designed to control the speed of the fan, turn on or turn off lighting. The electronics switches are controlled by using the NPN transistors and relay. The speed of the fan is controlled by using the different voltage when the relay is swap the input voltage at the different voltage.
The remote will be design using buttons to represent the control activities such as turn on or turn off, the speeds. The Wireless will be using the RF module which is 315MHz. many op-amp will be use compare the result.
It will be using the C programming’s language, PIC-kits 2, simulation software, Dip-trace and other application software. The design will be fixing to the wall.
