// Description: this is a quick code for a POV display
//		implemented using the Arduino. It used 6 LEDs
//		connected to the pins.

  Slightly modified (1st Jan 2009) by Ben Harvey to work with 
  my flash pov array maker, from http://gomako.co.uk
  
  All I did was reverse the order of the pins to work with my
  array order in flash. All the hard work was done by
  Carlos Asmat at http://carlitoscontraptions.blogspot.com
  
  What to change to match your sketch:
  
  col_length - the number of LEDs in your array
  frame_len - the number of columns in each frame
  frame_num - the number of frames in total
  
  The rest of it you can muck about with as much as you want.

*************************************************************/

int pins[] = {1,2,3,4,5,6};	// an array of pin numbers
int col_len = 6;		// column length

// customizable parameters
int timer1 = 4;			// time between columns
int timer2 = 20;		// time between frames
int timer3 = 0;			// time between drawings
int frame_len = 5;		// frame length
int frame_num = 7;		// number of frames
// data corresponding to the image to be displayed
int data[] = {0 ,1 ,1 ,1 ,1 ,1 ,1 ,0 ,0 ,1 ,0 ,0 ,1 ,0 ,0 ,1 ,0 ,0 ,1 ,0 ,0 ,1 ,0 ,0 ,0 ,1 ,1 ,1 ,1 ,1 ,1 ,1 ,1 ,1 ,1 ,1 ,1 ,0 ,0 ,1 ,0 ,0 ,1 ,0 ,0 ,1 ,0 ,0 ,1 ,0 ,1 ,0 ,1 ,0 ,0 ,1 ,1 ,0 ,0 ,1 ,1 ,1 ,1 ,1 ,1 ,1 ,1 ,0 ,0 ,0 ,0 ,1 ,1 ,0 ,0 ,0 ,0 ,1 ,1 ,0 ,0 ,0 ,0 ,1 ,0 ,1 ,1 ,1 ,1 ,0 ,1 ,1 ,1 ,1 ,1 ,0 ,0 ,0 ,0 ,0 ,0 ,1 ,0 ,0 ,0 ,0 ,0 ,1 ,0 ,0 ,0 ,0 ,0 ,1 ,1 ,1 ,1 ,1 ,1 ,0 ,1 ,0 ,0 ,0 ,0 ,1 ,1 ,0 ,0 ,0 ,0 ,1 ,1 ,1 ,1 ,1 ,1 ,1 ,1 ,0 ,0 ,0 ,0 ,1 ,1 ,0 ,0 ,0 ,0 ,1 ,1 ,1 ,1 ,1 ,1 ,1 ,0 ,1 ,0 ,0 ,0 ,0 ,0 ,0 ,1 ,1 ,0 ,0 ,0 ,0 ,0 ,0 ,1 ,0 ,1 ,1 ,1 ,1 ,1 ,1 ,0 ,1 ,1 ,1 ,1 ,0 ,1 ,0 ,0 ,0 ,0 ,1 ,1 ,0 ,0 ,0 ,0 ,1 ,1 ,0 ,0 ,0 ,0 ,1 ,0 ,1 ,1 ,1 ,1 ,0 }; 

void setup()
{
	int i;
	for (i = 0; i < col_len; i++)
		pinMode(pins[i], OUTPUT);	// set each pin as an output
}

void loop()
{
	int a,b,c;
	
	// go through all data for all columns in each frame.
	for (a = 0; a < frame_num; a++)
	{
		for (b = 0; b < frame_len; b++)
		{
			for (c = 0; c < col_len; c++)
			{
				if (data[a*frame_len*col_len + b*col_len + c] == 0) {digitalWrite(pins[c], LOW);}
				else {digitalWrite(pins[c], HIGH);}
			}
			delay(timer1);
		}
		for (c = 0; c < col_len; c++)
		{digitalWrite(pins[c], LOW);}
		delay(timer2);
	}
	delay(timer3);
