need to build BT device that sends keyboard commands

[jerdub]

I would like to build a small footswitch (box that sits on the floor) with two buttons on it. The buttons would send a "up arrow" and "down arrow" command via bluetooth. I haven't done much with small electronics before and would like some help just knowing where to start.

The box and switches are a no brainer, but I need to know how to program something that will send these signals.

I would really like for this project to be very minimalistic, using few parts and being very easy to operate.

Thanks!

It's non-trivial.

Bluetooth is a communications medium. Replace bluetooth with "smoke signals" and you'll see the problem. Not only do you need to produce the correct signal, but you need the receiver to interpret and act on them.

Perhaps the easiest approach would be to try to find a keyboard that connects via bluetooth and take all the electronics from this, then try to wire up your two buttons to do the same thing as the up arrow and down arrow keys.
