The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

Freeform circuit sculptures are a perfect example of the realm where electronic meets art. While many of these objects only serve aesthetic purposes, [Zachary Goode]’s X-Wing clock satisfies … ...

Reference circuit diagram of an Arduino-compatible LCD backpack is shown below. What follows next is information on how to use one of these inexpensive backpacks to interface with a microcontroller in ...

The idea here is to use a cheap clock from IKEA, wire in a bunch of LEDs, connect and Arduino, and then use the 1Sheeld to trigger color changes depending on the traffic time between two points.

Watch the video below to learn how and affordable IKEA clock has been transformed into a visual traffic monitor using a couple of LEDs and a little Arduino programming.
