Hi, I am a quite inexpert user, I am using an Arduino Uno and I was trying to use the matrix in the photo.
I tried to use codes with single chip on the matrix, connecting just 5 pins but it doesn't work.
Is there anybody that can help me in order to figure out how I can connect the matrix and wich kind of libraries I can use?
Thank you all
I don't know about anyone else, but I can't tell what the 16-pin chips are.
Looks like common Vcc, Gnd, CK (clock?), LE (latch enable?), then DIN on one side and DOUT on the other?
No current limit resistors in sight.
Looks like 2 x 74HC595 to me Bob.
So, one driving anodes & one driving cathodes until something burns out?
Yes they are 74HC595D, how can I use these?
