I need to to make 60 LEDs blink, each for one second.
one LED to turn on for a second followed by the adjacent LED while the previous one turns off and so on, till cycle repeats.
the main driver behind this is my 89c51 microcontroller. but the output ports aren't sufficient. and I can't come up with a way to multiplex so many LEDs.
I need to come up with a way to do that. my plan is to generate a signal from the microcontroller, and use some support circuitry to do the rest.
I was thinking of using an old fashioned counter, like the IC 4029. but I haven't used that before.
any suggestions?
