So I've looked online and found many conflicting answers, so I'm asking here. Please know that I tried to find a singular answer, but I trust the replies I get here more than random things on the internet. My question is this, I have an 8x8x8 LED cube, and an Arduino Mega. Is it possible to drive the LEDs using just a single MEGA, without any other hardware components (e.g., no LED driver chips or whatever)? I'm basically restricted to what I can get at my local electronics store (a Fry's), and so I can't use any fancy boards or specialized hardware. Any input would be greatly appreciated. Thank you everyone!
