Abstract

Voltmeter is a measuring instrument, used to measure the voltage difference between two points in electrical network. Generally there are two types of voltmeters – one is analog voltmeter and the other one is digital voltmeter. In analog voltmeter a pointer moves on the scale to represent the voltage. Digital voltmeter directly displays the voltage in digits with the help of analog to digital converter. This article explains you how to design a digital voltmeter in two methods 1) using 8051 microcontroller and 2)the other using IC L7017.
