A few days ago, Arduino just released a "start pack" for Android developers: http://arduino.cc/en/Main/ArduinoBoardADK
The Arduino ADK is a microcontroller board based on the ATmega2560 (datasheet). It has a USB host interface to connect with Android based phones, based on the MAX3421e
I have been searching again and again for tutorials or something in order to begin Arduino programming, and I am looking for very good tutorials, maybe some kind of "hello light" that would make a light blink on the card with a button on my Android device.
Have you got some links, fan blogs, other information about that topic?
I, of course, know the Arduino website and Android developer documentation, but they are quite over-complicated...
