| Oct 8, 2015 at 18:20 | comment | added | Gerben | If you use shiftregisters, and don't do any multiplexing, you probably don't want to run the leds at their maximum brightness. Running them at 5mA will probably be more that bright enough. That would, in worst case, mean 64*5=320mA. Which is not that much, though I'd suggest using a 5v adapter, as the tiny voltage regulator in the nano board probably won't handle that much current without getting extremely hot. You can easily find 5v usb chargers that handle upto 2A. | |
