MikroElektronika Arduino UNO Click Shield
The BrainPad has sockets for plugging in click boards.
This video talks about the technology behind SPI bus, shift registers, and serial-parallel data. It uses the LED ring click on the BrainPad.

The same code used above with the BrainPad can be used with FEZ and the Arduino UNO click shield. Simply, change the pins from BrainPad to FEZ. The pins are labeled right on the shield. For example, the
CS pin on socket 1 is labeled
