title: Blink an LED on my Arduino ADK
body: <p>I'm having some problems with my Arduino <a href="http://developer.android.com/guide/topics/usb/adk.html" rel="nofollow">ADK</a>. I just want an app that blinks an <a href="http://en.wikipedia.org/wiki/Light-emitting_diode" rel="nofollow">LED</a>. Send a signal from the app, and read in the Arduino. But I'm having some problems, like the <code>com.android.future.usb.accessory</code> library error. </p>
