Battery Indicator

The circuit consists of VCC portion of PWR_IN on the Arduino connected to a 51kOhm resistor and the GND connected to a 39kOhm resistor. The individual values should be 50kOhm and 40kOhm.

Connect the 51kOhm resistor to the 39kOhm resistor to form a loop. At the center, between the two resistors, solder in a wire. This wire will connect to Analog 5 on the Arduino. Cover all exposed wires with electrical tape and shrink wrap the entire line. This should appear to be a thick arch connecting PWR_IN with Analog 5.
