Hi all, I would like to make a small unit which basically has a few buttons which when pressed triggers an LED to show the selected button and also send the information of which button was pressed via bluetooth to a computer.
Will a single ArduinoBT module achieve this? And has anyone seen anyone write code for this? I have looked through various threads and haven't quite found what I am looking for.
The cheapo BT modules I allude to are all the same size, and about as small is you will ever get to go with Arduino.
If you are worried about size, the problem will be the Arduino, not the bluetooth. There are versions of Arduino that I know nothing about except that they are a lot smaller than normal. I understand the Pro Mini et al are about the same size as a bluetooth module and I'm sure they would make a good combination with it. I believe the only thing you need to be a bit careful about is running a 3.6v module like the JY-MCU off 3.3v.
One bluetooth device works much the same as another, i.e. serial in, wireless out, but, apart from questioning why you would need anything else, I can only comment on the ones I have described.
Sorry I wasn't clear, what I meaning to ask is if ArduinoBT is arduino with bluetooth integrated and might be more compact. I will definitely do some more research into smaller arduinos as size is fairly important to the project.
