Hi there, I bought an 8x8 LED matrix. The tutorial says to wire up each used pin of the led matrix to an individual out on the arduino. To me this seems a little basic (which I'm sure is the point of the tutorial), but I think I'd rather like to try an encoder. The problem is, I'm sure my terminology is wrong!
The forums say to use shift registers. I googled them but was having trouble understanding what they do. To me, it sounds like they are flip flops whose state gets pushed over one spot every time you add a "bit"; just like a shift register in C or assembly (MIPS).
but what I need is an encoder. a binary encoder? something that will convert my binary input to a bigger output.
are these the same thing? if not, what is the encoder called?
please and thank you, marco.
