So, what happens when we send a set of data to the LCD Device? Our resulting sketch will be almost simple. The most inspiring source to make this project comes from a blog post by Chris Parish ...

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 … ...

The coil leads were disconnected from the clock circuit and connected to digital inputs of an Arduino. With a few random() calls, the clock keeps accurate but random time.

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.

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 ...

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.
