I ordered the remaining 6 additional P7 (5mm LED version) 3216 RG displays this week to complete my 2 sets of 4 (8 total) display. I hope that a single Arduino can handle this many displays.
[1][2][3][4]
[5][6][7][8]
How do I program in a configuration like this with 2 sets of 4 displays (as far as the clocking, etc.)?
