Google picks Arduino for Android Open Accessory “kit”…

From the beginning, Android was designed to extend beyond the mobile phone. With that in mind, we’ve developed Android Open Accessory to help developers start building new hardware accessories that will work across all Android devices. We previewed an initiative called Android@Home, which allows Android apps to discover, connect and communicate with appliances and devices in your home. We also showed a preview of Project Tungsten, an Android device for Music Beta to give you more control over music playback within the Android@Home network.

A USB micro-controller board that is based on the Arduino Mega2560 and Circuits@Home USB Host Shield designs (now referred to as the ADK board), which you will later implement as an Android USB accessory. The ADK board provides input and output pins that you can implement through the use of attachments called “shields.” Custom firmware, written in C++, is installed on the board to define the board’s functionality and interaction with the attached shield and Android-powered device. The hardware design files for the board are located in hardware/ directory.
