i just got my arduino yesterday, cant wait to make my cube :)
-
good!

Hi can you post a scheme of this led cube?
-
@robertsgg Absolutely right. Diodes generally drop 0.7v forwards and LEDs tend to drop much more, generally in the range of 1.5-3v. White and blue LEDs are generally in the range of 2.7v. I tend to use 100 ohm resistors with blue and white LEDs. That gives 23 mA with a drop of 2.7v, probably as close as you want to go to the limit.

Bring that to a rave

HI! may i know the program of this??
-
i like how you had the IPC sticking out of the project box. easy access, nice.
-
@portreathbeach Not all of the 5 volts is across the resistor. You are probably dropping 3 volts across the LED. (2 volts) / 220 ohms = 9.1 mA.

How many volts to run the whole cube?

excelent job!!!
knowing that it is multiplexed, how much can I rise the curren of the leds?? thank you

I used 220 ohm resistors, so 5 volts / 220 ohms = 22.7mA
I think the LEDs are rated at 25mA. They are bright enough without any more current.

Are that normal 5mm LEDs?
looks like big 10mm or so

They are 5mm ultra bright LEDs
