Design and simulation of LED digital voltmeter with whole hardware circuit based on proteus
In order to strengthen and improve the basic hardware design ability of electronic technology enthusiasts and electrical class
a LED digital voltage meter of directly current is designed in this paper
which is composed of whole hardware circuit without programmable control. The designing and analyzing method of the sub module is used to design and simulate every module according to the system debugging order on the EDA platform of Proteus. These modules are separately A/D conversion module
clock module
shift counter module(binary to BCD conversion module)
start and reset module and LED display module. The system design task requirement is realized by designing and simulation on Proteus and by actual circuit welding and debugging with modules. This kind of voltmeter has the advantages with low measurement error
low cost and easy to carry and so on.
