Hi everyone, I'm a occasionally arduino user and i need to make a project that i think it's very hard:I need to plug a very important number of led on arduino (approximately 600) and i need that each led will turn on and then the same led will turn off when the next led will turn on...in this way i want to create a "led chain".At the moment that arduino has not more i/o port...how i can to plug this big quantity of led in this way?
Crossroads suggestion looks the easiest way to go
with Shift registers you'll need to provide resistor for every common anode/cathode and transistor banks to supply power
Mouser are quoting $13 and our cheapest price here is about $10.
