HSC2011/Hardware

Specification

Nodes are supposed to be equipped with:

• RF transceiver
• 4 buttons, labelled with digits, letters, colours (probably red / blue / green / yelow) and symbols (playstation style?)
• a LED for each button in matching colour
• an RGB LED
• a buzzer
• a 1-wire interface for authentication buttons (iButton)

For ease of development, they also get a serial interface.

Implementation

Both for development and for the final version (as far as we know now), an ATMega168 is used; for development, encased in an Arduino, which also binds the RX/TX pins to a USB serial interface.

As an RF module, RFM12B and ZigBee style devices are being considered.

The wiring is defined in an eagle file in our yet-to-be-set-up SVN repository.
