I made two electronic circuits each consisting of a 555 Timer, a CD4017 and 7 leds in the shape of what you'd find on a dice. They work great and all, but I want to "compare" the results of both and indicate which output is higher by lighting a LED near the circuit which has more LEDs lit. I thought of dragging a wire from each anode of the leds and conjoining them and then using a comparator of currents?(if that exists), I need your help on this part. Any ideas?
