Wireless button presses sent to the PC

I'm new here. I tried to search for things like button presses to the PC, etc. but no luck. So I would like to make a little floor pad with 9 soft buttons, then try to connect it to an arduino BT and then to a PC over a BT USB dongle.

I need a programm written in C# to then be able to pick up this data and tell me exactly when any of the 9 buttons is pressed, if it is being held down, and when they are released. I would also like to have an LED on the pad itself go on, as each button is pressed, for good trouble shooting, and a more impressive display. I hope I'm not biting off more than I can chew here, but you know, "the dream is alive." :slight_smile:

Have you gotten the PC program developed? That maybe the hard part. You can start developing the arduino part using the serial monitor to display the results. You can start by working on button and LED code.
