Digital voltmeter using Arduino UNO Range:0-50 volt Using SIMULINO UNO

This is a simple project showing you how to make a digital voltmeter using Arduino where the readings are displayed in a Liquid Crystal Display LCD20x4. The proposed voltmeter design can read up to 50V. We are using analogue to digital conversion process. Arduino microcontroller equipped with 10-bit analogue to digital converter (ADC). This means Arduino can read 2^10=1024 discrete voltage levels.In this pr ...
