  • I understand that the 3 to 8 decoder and the extra pin from the microcontroller selects 1 of the 9 rows of LEDs but how does it know which of the 3 LEDs in that row to select? I apologize for the trivial question but my friends and I have been analyzing this for some time and we’re still scratching our heads @_@.

No public wish lists :(
