Hi Im back with another LED current question (I can hear Gus sigh allready)
I have added a LED cube project in the Wiki (link removed) And as I say in the description I cant really get the speed of flipping the LEDs on an off fast enough to get a good POV. So is there a faster way of doing this in NETMF?
But back to the LED current.
With the 220ohm resistors that I have got on the 5mm LED it seems to work ok. But what will happen if I would try to turn on all 9 LEDs for a level on the same time? Will the current fry the board?
Or even the whole cube that would mean 3 LEDs in parallel sharing a 220ohm resistor.
