Hmm... why not use a simple decade counter? and instead of using an LED, re-route the output to keep the appropriate led's on in order from 0-9? Here is a simple circuit here, but just try to think on how to 'convert' it... ;-) http://www.aaroncake.net/circuits/counter.htm I will leave that part up to you :-D it is a very simple circuit and ready to take a pulse from a 555 timer too. just remember to keep your voltages within limits.
