To start off we drew up a schematic then gathered the various components we would need including: Arduino leonardo clone, 3 large lighted buttons (red, yellow, green), 3 relay modules (to control the 120 VAC going to the lights), a solderless breadboard, 2 terminal blocks, and misc. Wires and connectors. After all the parts and the basic design was completed assembly could begin!
