Before I go further into this build I want to make sure I am on the right track.
I want to use 328P chip for control and will be using 74hc595 to control LED’s
After each 74HC595 I will use ULN2804A driver to take the load of them, after each ULN2804A I will Mount my current limiting resistor.
Supply voltage to each layer will be from a MOSFET or 2 parrallel transistors.
Worst scenario, each output from 74HC595 will drive 10 LEDS, that is why I use ULN2804a, but that will make it ground controlled. I just need to remember this when I build the cube.
Max current for each led is 30mA, but I am aiming to limit that at 20mA with resistors.
Can someone smarter than me (that would be everybody else but me) take a look at my attached diagram and see it it looks alright?
