I'm really excited about the Pi.
I've seen an arduino project managing 8 PWM, 20 relays and 3 or 4 temperature (DS18B20) and pH probes.
So far so good, works fine, but I'd like to work on something with more options around.
Say wifi, webcam, webserver, managing the app via android, touchscreen, etc.
Most of the above "options" work already on Pi (except maybe touchscreen).
But how can I achieve managing PWM, relays, probes with the Pi ?
Is there extension cards for that ?
I've checked the Gertboard, but I'm lost with the electronics language in the thread, I'm not sure of the features it'll propose.
Thanks for the help guys.
