Have you ever wanted to create a cool new hardware accessory for your Android device? But do you find the thought of writing Android code daunting?

Learning Android development can be overwhelming if you are coming from the much less complex world of Arduino microcontroller development. The Handbag project enables those with only Arduino experience to create acessories for Android devices without writing Android code.

The Handbag library for Arduino—which builds on the Android Open Accessory protocol—enables the user interface and functionality of an accessory to be implemented in an Arduino sketch. When a Handbag-compatible accessory is connected to an Android device the user interface definition is uploaded to the Handbag for Android application which then relays user actions to the Arduino sketch.

This session is presented by the creator of Handbag and the dual-display Nexus One project as seen on Make, Hack a Day and Engadget.

Attend this session and you will learn how to create Android accessories without the need to learn Android development first.

It’s like cheating on your Android accessory development test!

Philip Lindsay (also known as follower from ) creates tools to encapsulate the knowledge he gains from exploring and understanding technology in order to help others do their jobs more effectively. He translates technology.

In addition to teaching introductory Arduino workshops Philip has contributed USB and networking code to the Arduino eco-system.

When not exploring technology for the fun of it, Philip creates documentation, code libraries and example projects for SparkFun Electronics and other clients.

Tim O’Reilly once called Philip a “troublemaker” for his early Google Maps reverse engineering efforts.

Philip has a particular interest in the areas where design, art, craft and technology intersect.
