Schematic for a simple 3x3 LED Cube using the Arduino Nano
Schematic for a simple 3x3 LED Cube using the Arduino Nano.
You can find the code for the cube here.
This uses 9 IO pins sourcing current to control the 9 LEDs on each plane, and 3 IO pins sinking the plane's current to control which layer is active, therefore it uses the LEDCubeXZOutYIn class. (IO pins source/output current to the XZ plane and sink/"input" current to the Y layers) If you would like to change the wiring, refer to the instructions in the Nano-3x3-LED-Cube repository.

Nano-3x3-LED-Cube: common questions
What microcontroller does the Nano-3x3-LED-Cube use?
The Nano-3x3-LED-Cube is built around the Arduino_Nano_v2.x, from the AVR/Arduino family.
How many components are on the Nano-3x3-LED-Cube?
37 components, from 3 distinct parts. The full bill of materials is listed on this page.
Where can I download the Nano-3x3-LED-Cube design files?
From the UnsignedArduino/Nano-3x3-LED-Cube-Schematic repository on GitHub, which has the schematic; the links under Design files point to each one.
Can I use the Nano-3x3-LED-Cube design in my own project?
The repository has no license, so all rights stay with UnsignedArduino. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Nano-3x3-LED-Cube without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
