binaryclock atmega168pb

A binary clock i built using an AVR ATmega168PB and LED display matrix built using perfboard. Displays the current time of day as a 16-bit integer (a one is shown by a lit LED, a 0 by a dark LED). Becomes all 0's at midnight, a leading 1 followed by 0's at noon, and becomes all 1's at the equivalent of one binary second before midnight before the data overflows and it becomes all 0's once more (midnight, new day). One "binary second" is 1/65536 of 1 day compared to a normal second which is 1/86400 of one day. Another way to explain it is that a binary second is 86400/65536 seconds, or just over 1318ms.
