Abstract
This paper presents the Design and Implementation of Wi-Fi- based Ceiling Fan Regulator System using Arduino Nano board and an ESP8266 Wi-Fi Module. It is born out of the need to provide a flexible and convenient means of regulating the speed of a ceiling fan without resorting to the manual means of doing same. The components used are: An Arduino Nano board featuring an Atmega 328p Microcontroller, an Esp8266 Wi-Fi Module, a coil inside an old manual fan regulator, a relay board comprising of four relays, a 3.3V regulated power supply unit and connecting leads. The appropriate drivers were installed for the boards while the necessary libraries were included on to codes written using the Arduino Integrated Development Environment (IDE). The 5V power supply from the Arduino board was taken on to the power board for regulation using the LM 1117 voltage regulator. The RST terminal of the Arduino board and the GPIO0 of the ESP8266 module were connected to GRD. The codes were uploaded on to the flash memory of the Wi-Fi module. Any Wi-Fi device can be used to select the speed of the ceiling fan through an interface designed using html language. The system proved very efficient and reliable for both office and domestic use within the required range of 40 - 300 feet.
