DIY: A 3-Digit Digital Voltmeter (Atmega8)

Here's a simple digital voltmeter based on Atmega8 microcontroller. It uses the in-built A/D converter to measure the input analog voltage and displays it on a 3-digit seven segment LED display.

This same basic circuit can also be used to make a timer, counter, and a digital thermometer with some changes in the i/p side.
