the brains
24 el-wire wire pairs are controlled in this setup - 8 per I2C board. It should be able to handle 5 more boards fr 64 el-wire segments but I've only tested 4 boards so far. The MLK head only needs 24.
I also hacked in the motion detector (PIR - lower left) into the setup through the unpopulated xbee space on the daughter board. If no one is around to hear Martin talk does he make a sound?
