Smartphones gives us a wide range of applications that help us organize our selves, play and wake up on time, but if only there is a way to connect our phones to the real world to control hardware stuff like house lighting system or the garage door. Smartphones have a bunch of possibilities including sensors like GPS, accelerometers and temperature, a decent cpu for processing data but the most important feature a smartphone can give is its portability.
In 2011 Google starts a project called Android ADK: http://accessories.android.com/ the Android accessory kit, that can make your phone communicate to devices (accessories) by make a bridge between the power of android devices and the real world through a simple USB communication. This bridge can solve so many problems :D
So I thought to try it out with an arduino ADK board. The project I've done is to control a led and a DC motor From the Android to the arduino passing by xbee modules.
The next diagram explains entities communication:
The code has three sides:
- The Android side : sending commands through ADK
- The Arduino ADK Side: Receiving commands and send it wirelessly to other arduino boards with xbee
- The Arduino Uno Side: Receiving commands from xbee and control the DC motor and the led.
The hole project:
I'll be happy to answer questions in the comments
Thanks.
