I discovered Ciao after a similar project I worked on for Android was featured on the Make Blog: http://blog.makezine.com/archive/2011/05/use-android-open-accessory-without-android-programming.html http://blog.makezine.com/archive/2011/05/use-android-open-ac... Hangbag for Android enables people to create Arduino-based accessories for Android devices that support the Open Accessory protocol (recently announced at Google I/O) without writing Android code: http://www.labradoc.com/i/follower/p/android-arduino-handbag http://www.labradoc.com/i/follower/p/android-arduino-handbag I released an update the other day that packages the Arduino-side as a library and improves the API. Now you can write code like this: void toggleFirstLed() { // ... } Handbag.addLabel("This is a label"); Handbag.addButton("Toggle Digital Pin 4", toggleFirstLed); [A side observation: Easiest way to find about similar work that's been done before is to get publicity and then someone will point out: "Oh, yes, such and such did that here". :) ]
