Each transistor is connected to 1 of the 3 cathode levels.
-I calculated with this program: http://led.linear1.org/1led.wiz , that I needed 9*150ohms resistors. Though on the internet I found that most people uses ~220Ohms resistors. I'm not sure why they do that, so if anyone can tell me I would be thankful smiley!
Control question:If I want to lit up the whole cube, I need to do the following:...Or is this possible as well? (I'm newbie in programming as well ):-Select layer 1 (turn off layer 2/3)-Turn on all LED-Turn off layer 1-Select layer 2-Turn off layer 2-Select layer 3-Turn off layer 3
