Sorry for my late answer, here's the code. May it occur because of my "time- asking"? I'm using RTClib.h and I am always asking for the time at the beginning of the loop. Does this lead to my dark LEDs?
The sketch works well, the matrix shows the correct time.
While I'm uploading, some LEDs light up (always other ones). They light up very bright, so the mistake cannot be in the hardware.
I'd be very glad if somebody could show me how to handle the DS1307 module exactly!
