I am trying to design a t shirt riddled with LEDs, such as each LED will periodically light up.
Doing this with 10 groups of LEDs was simple enough : a 555 timer network provided a clock signal to a CD4017 decade counter, which dispatched signals to the 10 groups.
I am trying to do so with 20 groups of LEDs, but no counter longer than a decade counter exists. How would you do it?
I don't have the slightest idea what wonders electronic parts can do, so any tip, suggestion or idea is welcome
I have attached a truth table that would be one possible solution : if a part such as the one described existed, attaching one of these to each of a decade counter's output would effectively make a 20-counter.
