binwatch
A binary wristwatch.
The binwatch differentiates itself from other watches due to its unusual way of reading.
It uses 11 LEDs to display the time in binary.
It has three columns. The first shows the hours, while the remaining two show the minutes.
It keeps time using the NXP PCF8563 and uses an ATmega48PA to control everything.
I chose the ATmega48PA over the more common ATmega328 because of the lower cost and power consumption. Nevertheless, the ATmega48 does have less storage and ram than the ATmega328, so I had to make some sacrifices in order to simplify the code.
