******************************************
Program above is about to make the fan, light and radio work.. The relay is about to on and off the radio.. while for pwm is to set the signal that will get from the transmitter is going to 255 (higher) and 0 (lower). This is the final program and will be test to the circuit by detect the LED first as an output.
