Light-up blog # 1: Concept overview of the device

alrms

For this Build-a-present, I'll be making a cube that not only lights up in a Christmas-themed way but also play with it together with your family and friend.

The device has two modes that you can use: the mood light mode and the game mode. The RGB leds light up the top while the 8 x 8 led matrix is placed below. The default option is the mood light mode but if time permits, I think adding an imu sensor to check the orientation is a good option to let the cube know what mode is currently right-side up

Mode light mode

The mood light mode turns the cube into a mood lamp that lights up a random RGB color. The special with this lamp is that you can set the color of the light for the first box and the second box lights up the same color. You can use this to set what your mood is through the color. It's a cute way of communicating with your love ones especially those that cant go out because of the pandemic. My initial thought is to use encoders for this to set the light but I'm hoping I can do this an easier way.

Game mode

The game mode is for playing games with another player with the box. I'm thinking of two games, one is the Arrow dance where you have to press the button corresponding to the arrow displayed by the led matrix as fast as you can. As the game progress, the faster the arrows changes. The last one to keep pressing the right button wins. The next game is the Build-a-pine-tree where the player lights up each led that will make pine tree. First to form a LED Pine tree shape thru the LED matrix wins. Other shapes such as the gingerbread man or a smiley is another option I can incorporate in the game.

What's next?

I'd like to move forward with gathering up the parts needed for this as well as the casing that will served as the cube. For the size, I'd do a Arduino Uno-sized version and scale it down to a Arduino Nano to make it more portable. If by chance I win a Arduino Uno mini, I'd use that in one cube and an Arduino Nano in another.

  • Wonderful project idea. 

    I had used 8X8 matrix LEDs on a couple projects for eyes,at the time the available colors were red & white, with red being the standard supplied with a driver board. 

    Surfing, I found 8X8 LED matrix are available with WS2812 LEDs. That is too cool for school. 

    Will the cube feature qty 6 RBG 8X8 LED matrices ? Besides being awesome,  I'm looking forward to hear how the Arduino performs and programs with 384 LEDs.

    Right now, I'm pushing for actualizing the concept so I'll be focusing on red 8x8 LED matrices. I've seen Seeed Studios offering RGB 8x8 led matrices which I can use along the project pipeline once the initial concept is created. While a cube of 8x8 led matrices is cool to look at, it's an interesting challenge for me to what I can do with one 8x8 led matrix for the cube which is the focus of the project and make it fun. In a way, what will work on a single 8x8 led matrix can be scaled up to 2 or more led matrices.
