Arduino LED Cube

Created By Chris P.

This project is a cube of 64 LEDs that can be programmed to make all kinds of interesting animations and patterns! Its circuitry allows for LEDs to be individually addressed in the programming.

I have made an HTML/PHP program that utilizes checkboxes to write Arduino compatible code to light up LEDs. This program saves time, and is also pretty neat!

I have also added a Joystick and two pushbuttons as input devices that can be used in any way. I'm attempting to make Snake in 3D with the Joystick, but I hope to eventually publish this project as an open source kit.

Here's a video of me presenting my project.

Here's a video of the beginnings of the snake program.

System Operation Scheme

• The Arduino applies power to a programmed number of anode columns (my pins are 23-38)
• The Transistors grant ground to only one cathode layer at a time (pins 2-5)
• The use of 4x4x4 3D arrays allows the Arduino to light up different LEDs in different layers

Bill of Materials

• 3 packs of 25 diffused blue 3mm LEDs (75 LEDS, only 64 are used): https://www.adafruit.com/products/780
• 25 150 Ohm Resistors, for current limiting the LEDs
• 7 10k Ohm Resistors, to pull up the buttons and pull down the transistors
• 2 pushbuttons
• 2 2D Thumb Joysticks (1 used): https://www.sparkfun.com/products/9032?
• 1 Rocker On/Off Switch, wired in line with the power supply
• Arduino Mega
