Mechanical Dimensions
Assembled cube is of approx. of 10cm (l) X 10cm (b) X 12cm (h) dimension.
Understanding the Schematic
To easily understand the working of Rainbow Cube, a very simplified schematic is presented below. In essence, 64 RGB LEDs are arranged in a form consisting of 8 common anodes(positive pins) and 8 common cathodes(gtound pins) for each color Red, Green and Blue.
- The complete schematic of RGB Cube is represented in a 2D RGB LED Matrix form below.
- Numbers 1 - 32 indicates the pin number of the 2x16 pin header shown above.
- The RGB Cube inter-connection are presented in a block diagram format. This block diagram clearly shows how the 64 LEDs in 2D form are mapped into a 3D Cube form.
- The actual 3D positions of LEDs are marked in the below photograph.
- The X,Y coordinates of 2D RGB LED Matrix is mapped to the RGB Cube block diagram as follows:
- Locate the 2D-XY coordinate (X,Y) from RGB Cube block diagram
- Use these (X,Y) co-ordinates with (X,Y) coordiantes of RGB Matrix to know how the LED is controlled (i.e locating VCC and Cathode pins)
- For example: LED (Z,X,Y):(1,0,3) 's 2D-XY is (6,3). This LED's VCC is Pin 31. The R,G and B LED's cathode are connected to 12,25 and 4 pins respectively.
Rainbowduino v3.0
The Rainbowduino board is an Arduino compatible controller board with professional multiplexed LED driver. It can drive a 8x8 RGB Led Matrix or a 4x4x4 RGB LED Cube in common Anode mode. Rainbowduino v3.0 uses two MY9221 chips which is a 12-channels (R/G/B x 4) constant current Adaptive Pulse Density Modulation (APDM). Rainbowduino v3.0 has provisions for cascading more such boards with I2C interface.
Rainbowduino v3.0 is flashed with Arduino boot-loader and this makes it easy to program sketches using Arduino IDE. Unlike other LED drivers, this comes with a USB to UART (FT232RL) inbuilt for programming the sketches.

Application Programming Interfaces
In the above example, we have used few of the below APIs
init()
First we need to initialize the driver using init()
Usage:
To set a LED in the 3D Cube we use the below two APIs.
setPixelZXY(Z,X,Y,R,G,B)
To set a LED (Z,X,Y) we use setPixelZXY(Z,X,Y,R,G,B).
Usage:
setPixelZXY(Z,X,Y,24bRGB)
Alternatively a LED (Z,X,Y) can be set by using setPixelZXY(Z,X,Y,24bRGB).
Usage:
blankDisplay(void)
At times, it useful to blank all the LEDs. For this there is an API blankDisplay(void).
Usage:
Demos
setPixelZXY() Demo
- To understand the (Z,X,Y) pixel addressing let us see another example. In this demo, the Layer 0 (i.e Z-0) is painted Green and Layer 3 is painted Blue.

setPixelZXY() Random Colors Demo
- In this demo, all LEDs are painted with some random color. After five seconds of delay, the whole cube is repainted with random colors.
