This project incorporates communication between an Android Phone and the Arduino using Bluetooth. The basic functionality includes taking messages from an android phone, displaying them on an LCD display, and taking a 'l' message sent and utilizing it to turn on an LED. Also, this project will allow you to send messages to your phone using the serial monitor when the Arduino is plugged into a computer.
The presentation material and the code can be downloaded at Android Interface.
