Example Code for Arduino-Coordinate LED Control

Hardware Preparation

• DFRobot Gravity:Full Color 4x4x4 Light Cube x 1
• 5V/1A DC power supply (common mobile phone charger and charging treasure) x 1
• Micro USB cable x 1

Software Preparation

• Arduino IDE
• Download and install the DFR0606 LightCube Libaray Github. (About how to install the library?)

   DFRobot-DFR0606 Full Color 4x4x4 Light Cube
   TThis sample code is used to coordinate the way to open the light cube 
   of any one of the LED.
   setVoxel(int x, int y, int z,int r,int g,int b)
   x、y、z is the coordinate,r,g,b is the Color.

        setVoxel(x, y, z, r, g, b );
        
}

Result

After running the code, you will find that the bead at the position of the light cube (1,1,1) will flash purple with RGB value (139,0,139).
