I am rather new to this and as part of a hobby project I'd like to end up with a simple display showing a time counter. Starting at 0 and going up from there, being able to support several hours (so showing seconds tick by, then minutes and finally hours). So maybe have six 7 segment displays, counting up. This would be powered 'from the wall', after transforming the voltage into the fitting value.
I have seen some circuits that use 7 segment displays along with 555 components to create some sort of timer circuits but they seem quite complex in terms of size and component number.
Is there a way, perhaps using some more advanced/complex components, that I could achieve what I want?
I'd like to avoid overly complex circuits that depend on precisely measured resistors and capacitors to create counters that tick with the rate of seconds.
