The prototype is composed of an arduino microcontroller, a LED RGB panel. and a RTC module; the case was 3D printed to scale.
There are 4 alternative methods to display time:
– arabic numbering (24h), both hours and minutes are displayed with numbers;
– numbers for the hours and one pixel for each minute arranged in a column of 10 minutes each (total of 6 columns);
