Digital fuel gauge

Digital Fuel GaugeWhat happens when my fuel gauge stops working in my 30 year old car?….. I design and build a new one.

Based on the Arduino Uno R3, this fuel gauge has a 16 character x 2 line LCD display and is programmable! It supports a massive 5 tanks of practically any volume and will read and display the remaining liquid in nearly any type of tank, as long as the tank has a resistive type fuel sender unit.

You can even calibrate each tank separately, and they can have different fuel senders and volumes.


  1. Displays remaining liquid in litres
  2. Can be calibrated to suit nearly any fuel tank
  3. Bar graph to display remaining fuel in selected tank
  4. Runs off 6 – 20v DC (Recommend 7 – 14v DC)
