Hello
I want to control 6 (maybe more) 7 segment LED displays from an Arduino. Given my current level of knowledge (and what's lurking in my IC box) I know I could use
6 X 74HC595
Or
a MAX7221
The former seems like a lot of ICs for something relatively simple and the latter seems like a waste as the max handles in and out (IIRC)
Better solutions?
Thanks
Jim
