#How to make flip clock screensaver code

As always, the trick is finding some code which successfully initialises the display (including orientation). The clocks use a simple automatic DLS adjustment class which takes a table of start/end dates. As well as setting the date and time it configures the red/yellow bin cycle (or none) Pressing Set from time display goes to the configuration screen.

Pressing Adj from time display cycles through the faces (including a pseudo-face which randomly cycles through faces). The sketch uses all but around 100 bytes of the UnoвЂ™s program storage space. There was a little program memory left, so I squeezed in a very simple Pong Clock, again using code from an earlier project. The look is based on this font Triangle ClockДЄn adaptation of an eariler project with a triangulated irregular network (TIN) style face, more pretty colours. The LCD colours are appealing, so I experiment with coloured cubes. The LCD inspired me to add in some additional clock вЂњfacesвЂќ: The angles come from skipping every 4th row of the digit data, so itвЂ™s acos(3/4)=41В°, close enough to 45В°! The time digits change with a detailed 3-step animation (top flap at 41В°, 90В° and 131В°). ItвЂ™s alternate weeks and I keep forgetting (this display is optional). As a bonus, across the middle thereвЂ™s a blinking/flipping colon and also a coloured digit indicating the number of days until I need to put out either the rubbish bin (red) or the recycling (yellow). The time is in big digits across the bottom.

The main clock display is the day, date and month in smallish flip-style digits across the top of the LCD (landscape mode).
