1  Using Arduino / Interfacing w/ Software on the Computer / using arduino as a keyboard input on: April 12, 2011, 10:08:24 pm
I was looking to start a project using an arduino as a keyboard input and was wondering if this was possible using my arduino duemilanove and having it type a certain string of characters or use a keyboard shortcut such as control+shift+letter or just basic simulation of keyboard

im not really sure where to begin and i was wondering if there is any sample code for a basic hello world print
