ABSTRACT:
A ceiling fan and light assembly control circuit including a microprocessor controlled by a single-throw switch and an infrared remote controller operated to regulate the fan speed and the intensity of light. A 60 Hz square wave signal of cycle 16.67 ms is obtained from the alternating current power supply and monitored by the microprocessor. When the square wave signal is interrupted by switching the single-throw switch on and off quickly, the micrprocessor triggers a change in the operation mode of the ceiling fan and light assembly. The infrared remote controller can also be operated to control the fan speed and the light intensity when the single-throw switch is switched on.
