Step 1

Source the electronics. Here is a diagram of the controller box

Here is the complete controller installed:

Electronics Box

Gross Electronics:

Electronics Box - local hardware store
Extension Cord
- Or house wiring with Female Plug and Male Plug.
2 alligator clips for battery connection - auto parts store
House wiring box (blue box in picture above below the Arduino Shield - hardware store
Fuse holder - car parts store
12v quick connect plugs - 5 pairs - for quick-coupling to solenoids out of controller box - car parts store
Stranded 5A wire for solenoid connections
Spade terminals (10) for connection to solenoid terminals
Underground phone cable - makes very tough connectors for sensors
Potting compound
PVC pipe - with 1 end capped
Stranded Cat 5 wire for sensor connections
[5] Supermagnets -
