Paper Title
Advance Automobile Security and Locking System Using LEB and DTMF Technology

Abstract
This paper describes a method for advance automobile security and locking system particularly for bikes, which could be controlled through smart phone as well as ordinary non android phones. The whole circuit of the system could be installed inside the bike in such a manner that it would be very difficult for a miscreant to alter it directly. Low Energy Bluetooth technology and Dual Tone Multi Frequency system backed with a separate power supply constitutes a simple, economical and congestion free security system with high reliability. The initial lab level test for proposed circuit has been conducted and results are very satisfactory. Arduino board and IDE have been used for all simulation and practical test purpose. Keywords - Bluetooth, DTMF, Arduino Pro-Mini, Arduino IDE, power supply, automobile security, Vehicle theft.
