I have two main plans for my Gameduino - the first is about learning how to use C to create some games and interactive programs (slowly working my way through the Gameduino book). My second is to try creating a touch-screen interface for a Raspberry Pi (I'm thinking of an online radio/news feed/calendar).
I've seen some pictures on the Gameduino Twitter feed of the shield connected to the GPIO pins on the Pi but with my level of electronic muppetry I'm not sure which pin to connect where or (frankly) how to start going about sensing inputs or displaying outputs (do I use Python, Arduino software, something else?). Thus far I've been doing inputs and outputs with my Arduino and headless webserver type stuff with my Pi.
I'm not expecting answers on a plate, of course, but a pointer in the right direction to get me started would be great if anyone has some good advice. I'll happily write up my progress for all to laugh at see.
