Digital Voltmeter
This project gives you a digital voltmeter which can measure voltage from 0v to 25V DC. The values are displayed over the 7segment display. Atmega8 is used and the internal ADC is used to measure the DC voltage. The resistor network is used to reduce the input voltage to the 0-5v.
