Arduino Bluetooth Control Smart Home with Firmata This project you can control 8 channel relay outputs via Bluetooth with Android device and Arduino board + Bluetooth Module. About Arduino code use Firmata Library so, you don't need to write any arduino code just flash to arduino board because Firmata library is built-in in Arduino IDE already. System Diagram Hardware 1. Arduino Board or compatible Board. 2. Bluetooth Module ( HC-04,HC-05 or HC-06 ) 3. Relay Board Option Regulator 5 V. DC 1 A for Relay Module Development Kits on ebay http://www.ebay.com/sch/marychanyanuch2012/m.html?
