Last week, I gave a talk + demo about using Amarino to make both Arduino and Android talk to each other in Bangalore Open source Hardware meetup
I have uploaded the slides which I used for the talk to my slideshare account and you can download it from there or view them here.
The slide also includes the schematic diagram for the circuit which I used for the demo. The source code that I used for the demo can be downloaded from the below links
Thank for your advice in Amarino Toolkit group
