Whats the fastest micro-controller that pretty much cab be programmed similar to an arduino out there that can operate sensors e.t.c?
Also look at the Chipkit uC32, which uses an 80 Mhz PIC32, I believe. Has an Arduino-
UNO form-factor. Not an ATmega, but uses the MP-IDE Arduino-compatible multi-
platform IDE. 80 Mhz and 32-bits is pretty fast.
If you're prepared to use C#, the latest netduino is apparently 168MHz.
