Thanks to the simplicity of the Arduino development platform there is almost an infinte range of clock projects you can make, and we love this example by Instructables member klraabe. Not only does it function as a normal clock, there is a motorised marble run on the top.
This can be activated when required at the press of a button, or move about as an alarm identifier - or even randomly for some extra fun. The enclosure was created with a 3D printer and also holds a line of LEDS which can blink in unison with the marble run.
Certainly something differenet and an excellent example of what can be done with a 3D printer and the world of Arduino. For complete details visit the clock's project page. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
If you need to add external hardware or devices to your next Arduino project, such as the Simon game described above - you'll need a protoshield to mount the external circuitry. When doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega we have a wide range to suit your application.
