PeterH:
If Powerpoint is running on Windows, the simplest solution would be to use Gobetwino to send keystrokes to your applications based on command strings sent from the Arduino. Gobetwino isn't available for non-Windows platforms (as far as I know) but it would be easy enough to write your own application to generate keystrokes.If you aren't committed to making your own hardware, you could probably get a wireless mouse for less than the cost of an Arduino.
Hi peter,
Thank you for your reply. Can you tell me if gobetwino will work if i make a standalone board. I want to use the 328 controller and a bluetooth which can send data to the serial port of the pc, this will be a standalone remote control sort of a device.
Now pressing the buttons will send some ascii codes, and can they be used with gobetwino?
