## What is Arduino Meter?

Transform your device in a cheap precise voltmeter, ammeter and capacity meter using Arduino and HM-10 Bluetooth module.

The voltmeter is based on an external voltage source which makes measurements actually independent from the powering voltage and much more precise of the simple analog measurements usually used (range limited to 4.096v on UNO and 2.5v on Zero).

The application contains everything you need:

- Bill of materials (Arduino, HM-10, etc.)

- Electric Diagrams and Wiring Diagrams

- Arduino code

- User manual.

Supported Arduino boards: UNO, Nano, MEGA, Zero
