ABSTRACT:
A ceiling fan and light assembly control method and circuit that uses a single-throw switch or clapping of hands to control the fan speed or light intensity of a ceiling fan and light assembly. The control circuit obtains a 60 Hz square wave with a cycle of 16.67 ms from alternating current city power supply so that when the single-throw switch is switched off and then switched on immediately, a triggering signal is produced to drive a microprocessor, causing it to regulate the fan speed or light intensity of the ceiling fan and light assembly. Alternatively, when two or three continuous claps are received by a microphone, the microprocessor will be triggered to regulate the fan speed or light intensity of the ceiling fan and light assembly.
