Hi, I'm trying to make a simple binary clock using various schematics that I've found online as a reference ( http://www.instructables.com/id/Full-Binary-Clock/?ALLSTEPS ). In the process, I'm trying to also understand the logic and figure out ways to improve the circuit. I'm very new to electronics…

Binary Clock - ATTiny85 + 74HC595 + ULN2003

Turf the 74HC595 + ULN2003; use a MAX7219.
