Step 3Put it together the hardware
I used three project boxes
* one large box for the electronics
* one medium box for the relay circuits (a mix of low voltage and high voltage)
* one small box for the high voltage connections
Make holes in the boxes where screws can hold them together.
Also make holes where wires can go between the boxes.
The small box also needs holes where wires can be hooked up for installation.
The medium box needs a hole for attaching the 9V battery holder.
The large box needs holes for the USB connector of the Arduino and a hole for the power jack.
The lid/top of the large box also needs holes for the LEDs, the switch, and the LCD.
