Finally made my first useful application for Arduino after so many breadboard prototyping - a 4 digit clock. It is made using an Arduino, DS1307 realtime clock, four 35mm 7-segments LEDs and driven by four 74HC595 shift registers. The fun part of this is that I can customize the behavior of the di…
