Arduino and rainbow shield example

Just a couple of rainbow shield examples that will randomly light up the various LEDs with different colours

[codesyntax lang=”cpp”]

#include <Rainbowduino.h>

void setup()
{
  Rb.init();
}

unsigned char x,y,z;

void loop()
{



     Rb.fillRectangle(0, 0, 8, 8, random(0xFFFFFF)); // draw a filled rectangle line from (0,0) of length and width 7 pixels
     delay(1000);
     Rb.blankDisplay();
  
}
