Description

This is really a cool little device that not only allows you to measure current, but voltage as well. With a little multiplication, you can even measure power.

In terms of voltage, you get to blow right past the Arduino 5 volt limitation. In fact, you can measure up to 26 Volts DC.

At +/- 3.2A, current measurement range is suitable for most smaller measurements. In other words, you can measure in excess of 75 watts of power. More about the board: https://www.adafruit.com/product/904

Enjoy it!:)
