Redesign is a recursive process...still looking for the base case...

A project log for Home Automation System (to rule them all!)

Open automation system, starting with lights and occupancy sensing and expanding to encompass anything that has wires or electrical contacts

So this horrid jumble of wires was one of my first attempts at developing the low level protocol.

At top right is a Teensy 2.0 acting as the master node, controlling a set of ATTINY2313 slave nodes. One has an IR motion sensor, and another has transistors switching red, green, blue, and white LEDs being used as place-holders for the high current LED drivers of a light fixture. The communication protocol has gone through several iterations since I wired up this hardware, so it's back to the drawing board now...
