Description: The issue is the use of a single-chip digital voltmeter designed to measure the 0-5V DC voltage between the value of four digital display, the use of fewer components. External analog voltage input to the A/D converter part of the input into a digital signal converted by the ADC0832, transportation to the microcontroller. Then by the microcontroller to the digital control digital signal, to control its light, which shows the number. In addition, this article discusses the design process used in software and hardware environment, such as debugging problems.
