Remote Fan Speed Control Circuit

The remote control is a cheap nec format remote usually supplied with small dvd players.

Remote fan speed control circuit.

The unit provides 10 way speed control from 0 to 9. The enter key is used to switch on or off the fan. Arduino ir remote in this tutorial you will learn how to control the speed of a dc fan using ir remote optocoupler tip122 ir sensor and arduino uno or mega. Nowadays all consumer electronics appliances or equipment has remote control facility for easy and convenient operation.

Previously we have posted very interesting project on fan regulator called light controlled digital fan regulator that uses torch light to control the speed of fan. The circuit is powered by regulated 9v. Ir remote controller fan regulator using at89c2051 is a simple circuit which can control the speed of fan you can also use this circuit to control the intensity of light. In this tutorial you will also learn how to find the ir codes of any remote controller.

The ac mains is stepped down by transformer x1 to deliver a secondary output of 12v 0 12v. Buying a remote controlled fan slightly increases the cost of the fan presented here a circuit to convert your ordinary pedestal fan into a remote control pedestal fan without using any. Three buttons are used to command the circuit. Using this circuit you can change the speed of the fan from your couch or bed.

Normally pedestal fan has a mechanical switch to control the speed and oscillation. Infrared receiver module tsop1738 is used to receive the infrared signal transmitted by remote control.
