3D LED Matrix Art

Inspiration

We were all excited to try something new. Building a three dimensional display and programming for it is something all of us

What it does

A 3x3x3 matrix of LEDs light up in a preprogrammed way, individually controlling the LEDs through a system of columns and rows built out of the cathodes and anodes.

How we built it

We soldered LEDs into three 3x3 layers. These layers are then connected to an Arduino, which we programmed to control the matrix.

Challenges we ran into

• Lighting up several LEDs at one time.
• Differentiating between the 3D layers.
• Controlling the voltage of the ground lines.
• The limiting number of Arduino Digital I/O ports, which prevented us from individually controlling one third of the layers.

Accomplishments that we're proud of

• Designing and wiring this project as a team was a satisfying experience.
• Learning what we could improve upon next time.

What we learned

• How to utilize the skill sets of those around us and work together to solve a problem.
• We could have better organized our design and problem solving steps to prevent the issues we dealt with later on.

What's next for 3D LED Matrix Art

• Expanding the scale of it with programmable RGB LEDs to create more art.
• Using XOR gates or multiplexers to control the ground and power lines, hopefully preventing the issue caused by lack of digital I/O.
