Digital fuel gauge

What 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.

Features:

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)
