Quad-channel Volmeter on an Arduino

Arduno Uno and most (if not all) derivatives has an Analog to Digital Converter (ADC) which is basically the thing that connects the digital world to the real world. This project walks us through the processes of making a quad channel voltmeter using an Arduino, some resistors and a 2x16 liquid crystal display (LCD).

The resistors are configured into a voltage divider to attenuate incomming voltages to the levels that the arduino can measure - the Arduino program will then cycle through the four voltage dividers measuring the DC level on each output and displaying it on the 2x16 LCD screen.
