This is a simple digital voltmeter project mainly focusing on designing condition circuits and demonstrating a use of analog to digital converter (adc. Now it's easy to make digital voltmeter using 8051 micro-controller and adc- 0804.
In this project, i'll show how to design a digital voltmeter using 8051 microcontroller and also explain its working voltmeter is a measuring.
This is a simple digital voltmeter circuit diagram using 8051 microcontroller we can also call it as analog to digital converter it's range is 0v to 5v. A simple 0-5v voltmeter using 8051 is shown in this article this digital voltmeter adc and seven segment display can be interfaced to 8051 to obtain a digital readout of the of the adc is interfaced to p10 of the microcontroller control.
Here atmega16 measuring the current and voltage by inbuilt comparator previous post described how to read adc value click here two adc.
