To do this in Arduino/C code, a new intermediate position for the servo is specified for each main loop until it reaches the final position.

The clock’s electronics rely on an Arduino. The issue with an Arduino, of course, is that the time base isn’t always good enough to keep time over long periods.

To make things a little easier on yourself, Arduino shield-maker 1Sheeld shows off how to hack a clock to change color depending on traffic conditions.

You'll need an Arduino, of course, and you'll also need a pair of laser pointers, a few servos and motors to make the lasers move as time passes, and of course, the IKEA BLANDA salad bowl ...
