The $22 kit includes an Arduino-BLE board and 6-pin header that should be fairly broadly applicable for building Arduino-based hardware that can communicate with iOS devices.

The truth is that [Kerimil] didn’t spend forever learning Java and programming the app. Instead he’s showing off the power of App Inventor to get your Android controls up and running fast.

The Arduino gets the fuel consumption readings from a Microstream OF05ZAT fuel flow sensor. The Arduino processes the data and then transmits it to a smart phone via a Bluetooth module.
