A BASIC D'Arsonval meter is what gives an Analog Voltmeter..what you can do is measure the voltage drop using a microcontroller's ADC and then to the same controller have a seven segment LED display. Have the 7 Segment Lool Up Table inside the controller | ||

i've seen one cct but can't quite remember where i saw it, it used a microcontroller and LCD, that, i can tell you is quite complicated and somewhat above your specifications. try google up things, i believe you'll come up with something.

i tried 'quoting' both digital and analog... 8) BTW a book by Carl Berqquist has a project on Seven Segment DC Voltmeter using a PIC. I think there is an application note too.. | |||

i just couldn't find question in his/her post. i wasn't sure which part of building electronic project was considered a problem. complexity? that's relative and too broad... each project will have something to appeal some newbees and scare the others. some don't like soldering, some hate programming, some would do anything with code but can't stand multiple components interacting with each other, some will buil anything you want if you give them instructions/schematics (some are making their own Appolo guidance computer). how simple "simple 7-seg voltmeter" has to be? one digit? soooo zeeshan353, how can we help you? | ||
