Abstract

The light level in a room has a huge effect on one's mood and productivity. Lighting can contribute to your alertness and awakeness in the mornings, and it can either entice you to feel tired or keep you up all night. With all of these discoveries on the effects of lighting, it is becoming more and more important to be able to control lighting. In this paper, Bluetooth controlled AC dim light is constructed using TRIAC. The android application is developed using JDK in Android Eclipse which will control the on off function of the light bulb. Bluetooth wireless communication has been rising in popularity nowadays due to its low cost and wide range of applications. Moreover, most modern phones have Bluetooth, making it excellent controllers for Bluetooth supported devices. Serial data sent from the Android application is received by the Bluetooth receiver interfaced to the Arduino. Zero cross detection method is used for TRIAC gate trigger and Arduino uses serial data to generate appropriate pulses at a specific angle for TRIAC. Isolation between Arduino and ac source is considered and overall system is implemented using simulation and practical approaches.
