I want to make a device which will send a data to a mobile phone which is connected using Bluetooth.
Here is the thing: http://www.youtube.com/watch?v=g0qARDGJj1w.
I want something like this. The problem is I have no electrical background. But I have theoretical knowledge as I had a few electrical subjects in college.
The problem is: I don't understand what should I Google, precisely. Just throw me in the best direction so I don't get lost and don't waste time. Give me a basic idea or something that will motivate me.
I don't want the exact thing shown in video. I just want following thing to happen at least:
The user pushes a button, read what that button is for (say it is for the letter
'A'), then the mobile phone will show the letter
'A' in some app, e.g. notes.
Here I am considering data could be sent over Bluetooth, and the mobile phone is an Android device.
