# Panneau LED
## Objectif
>Afficher l'heure sur le panneau led

##
### Montage:

>Avec ce montage nous pouvons lier notre arduino avec notre panneau led . Apres on connecte notr'e arduino a notre pc pour lui donner un code
### Code:
>#include "SPI.h"
#include "DMD419.h"
#include "TimerOne.h"
#include "Arial_black_16.h"<arial_black_16.h>
// you can remove the fonts if unused
#include "SystemFont5x7.h"
#define DISPLAYS_ACROSS 1
#define DISPLAYS_DOWN 1
/* change these values if you have more than one DMD connected */
DMD419 dmd(DISPLAYS_ACROSS,DISPLAYS_DOWN);
void ScanDMD()
{
dmd.scanDisplayBySPI();
}
void setup()
{

Timer1.initialize( 5000 );
/*period in microseconds to call ScanDMD. Anything longer than 5000 (5ms)
and you can see flicker.*/
Timer1.attachInterrupt( ScanDMD );
/*attach the Timer1 interrupt to ScanDMD which goes to
dmd.scanDisplayBySPI()*/
dmd.clearScreen( true );
/* true is normal (all pixels off), false is negative (all pixels on) */
}
