Arduino Binary Clock Display

Binary Clock is a clock that displays the current time in binary or decimal using a LED display. It really does not serve much of a practical purpose, unless your goal is to display the time in a strange format.

It is a LED clock built using the Arduino including controls for setting the time and the LEDs off. Each hour and minute digit is represented in binary form.

It is a 6 by 4 display of neon tubes that are directly driven to avoid dimming due to multiplexing. The design is based on the ATmega328 developed on an arduino. A 24 bit shift register drives a series of MPSA42 NPN transistors to actually drive the displays.
