Would you know of any resources to build a little led circuit like that on a breadborad, with standard components, that could be powered by a Pi?
In smaller dimensions of course, but even 4*4 would be interesting for educational purposes. The things I found online all used pre-built led boards which is less interesting I think.
A MAX7219 is an LED driver that can power an 8x8 grid of LEDs, so you could do the full 16x16 with 4 of these, or shrink down to 8x8 with just one. Then it's just a case of wiring up the LED matrix and connecting the MAX7219 to the Pi.
