Process

Step 1: First Working Prototype with Neopixel

For our first working prototype, we want to create a set of two connected Neopixel devices. If one presses the button, the corresponding LED will light up on both devices.

Step 2: Get Familiar with LED Matrix

To learn how LED matrix works, we referred to the code and examples by Chrisloris ( https://github.com/chrisloris/LedControl-MAX7219-MAX7221). In this step, we successfully implemented a simple demo in which we can control the movement of LED dots on the matrix. Here is the code for this step:

Step 3: Connect Two Devices

Step 4: Design the Cubes

We made two boxes with foam board and used them as the containers of all the components. To make the product more adorable, we painted each cube with different colors.

Step 5: Assemble the Final Prototype

The biggest challenge we met here was the circuit shortcut. Since the cubes are small and the wires are easy to be pulled out from the breadboard, we used tapes to stabilize them, while resulting in wires touching each other. Finally, we solved the problem by removing the tapes.
