Fan Speed Control Using Remote and Android

Abstract

The project focuses on creating a sophisticated system to regulate the speed of an AC fan utilizing both an infrared (IR) remote control and Bluetooth technology. The primary goal is to enable users to adjust the fan's speed remotely and effortlessly through two distinct methods. The system integration involves a series of hardware components, including an IR receiver module, Bluetooth module, microcontroller, motor driver, and the AC fan unit. For IR remote control functionality, the microcontroller is programmed to interpret and decode signals transmitted by the IR remote. Specific commands from the remote control are linked to various speed settings of the AC fan. Users can manipulate the fan speed, increasing or decreasing it based on the signals received by the microcontroller. The motor driver acts upon these commands, adjusting the fan's speed accordingly. Simultaneously, Bluetooth integration enables remote control through wireless communication between the microcontroller and a Bluetooth-enabled device, such as a smartphone or tablet. These commands are received by the microcontroller via Bluetooth, enabling an alternate method for fan speed adjustment.
