Arduino Battery Gauge – Input Voltage Measurement Board

Here’s a short little post to show something I made a few years ago.  It’s a simple, tiny board with a couple of resistors that is used to measure the input voltage.  It uses a simple voltage divider to reduce the voltage from the raw input pin and allow the conveniently close analog pin to read it.
