There is a single data line with a very timing-specific protocol.
Since the protocol is very sensitive to timing,
it requires a real-time microconroller such as an AVR, A rduino, PIC, mbed, etc.
It cannot be used with a Linux-based microcomputer or interpreted microcontroller
such as the netduino or Basic Stamp.
