Simple 7-segment LED display

[Macwarrior]

Hey there.

I'm working on a project which needs to indicate a timed event at a remote location - basically, it's a mechanical timer, where each second can be indicated by a bell or flag popping up or something, initiated by the mechanics of the timer itself.

I'm using a steel ball to indicate the time. I have a 7-segment LED display sitting around, but (aside from a mass of wires streaming out of everywhere, activating each segment) I'm not sure how I can build a circuit to have it display numbers.

I'm looking for a circuit that can take a trigger event (say, a ~500msec pulse of electricity) and use that to update the LCD display, moving it from 1 to 2 and so on. Is this possible using just simple ICs, or do I need more advanced logic? If it's not fairly simple (ie, no more than about 15 components), I'll just stick with wiring each segment on its own.


After searching, I found this post. Is that 4511 chip what I'm looking for?

I guess it's a bit of an excessive request, but thanks for any help.

This is fairly simple, just take a bcd decade counter for example **broken link removed** and just connect everything right, at least, if it can be a simple clock signal you take for input
