Before You Order

Check What You Already Have

Measurements Needed

Before ordering plumbing parts, measure your sink setup:

  1. Distance from shutoff valve to faucet connection
    • Measure with string or tape
    • Order braided hoses slightly longer than this measurement
    • 450mm hoses work for most sinks, but measure yours to be sure
  2. Thread type on your faucet connections
    • Usually 1/2" BSP in Australia (British Standard Pipe)
    • Take a photo if unsure - Bunnings staff can help identify
  3. Space under sink
    • Ensure room for solenoid valves (about 10cm long each)
    • Check foot pedal reach from standing position at sink
    • Allow space for water hammer arrestors

Shopping Strategy

💰 Budget Option (~$200)

  • Buy Arduino Uno only (not full starter kit)
  • Buy only essential components listed
  • Use basic project box (not waterproof)
  • Test extensively before permanent installation

✅ Recommended Option (~$250)

  • Buy Arduino Uno + jumper wire kit
  • Buy quality 12V 2A power supply
  • Buy waterproof enclosure
  • Get extra hose clamps and fittings for adjustments
  • Best balance of cost and reliability

⭐ Premium Option (~$300)

  • Buy Arduino starter kit (includes breadboard, wires, resistors)
  • Buy backup solenoid valves (in case one fails)
  • Buy quality waterproof enclosure
  • Get longer braided hoses for installation flexibility
  • Have spare components for future modifications
