hello, I'm a newbie and have no prior experience with arduino or microcontroller programming. For one of my course project, i need to send data/message/event from the arduino to my mobile phone (say android) via bluetooth as in the arduino board will have an external button/switch which when pressed should send an event to my application on android phone.
I did some googling and found Arduino BT and amarino as the right option for my project. And then there is BTShield v1.1 which is a cheap alternative (but i'm not sure about the interfacing). having said that, can anyone plz give me some pointers on the bluetooth programming part & some example codes on how to do this. Also, is it possible to embed a button/switch like stuff on the arduino board and as & when pressed, would it be possible for my android application to detect that press event?
