I am trying to do a project which requires me to control about 100 LEDs individually. I want to make a clock that has 6 columns of 10 LEDs that as the number in the time goes up, more LEDs will turn on. I would prefer just doing it with wires connected directly to the lights. I have looked into using an arduino, but they don’t have enough ports. Is there any way to do this? Maybe using USB?

Thanks,
