Fan light remote control circuit.

The wiring in the ceiling has three wires plus the ground white common black hot and red used for blue lead from prior fan s light kit. You can wire a new ceiling fan with a remote to a wall. Connect the green copper wires together. In the bistable mode output ic555 keeps two states either low or high.

It uses the 555 timer in the bistable mode. Connect white wires together. Tuck the wires back into the box. This remote controlled switch circuit can control ac loads such as lights fans etc through the remote handset of tv.

The circuit is powered by regulated 9v. The ac mains is stepped down by transformer x1 to deliver a secondary output of 12v 0 12v. Connect the lighting wire typically blue to the black fan wire and the black ceiling wire. Connect black wires together.

Using this circuit you can change the speed of the fan from your couch or bed. I have a ceiling fan that uses a remote control with wiring for the various features and only a common and hot wire lead. The circuit takes the help of a moc3031 triac driver stage for enforcing a hassle free and clean fan control through the remote handset. 12 volts includes led light st.
