MATERIALES:

• 1 Módulo 7 Segmentos.

CÓDIGO:

Opción 1 (Prueba de los segmentos):

void setup()
   {
        for (int i = 2; i<11; i++)
        pinMode(i, OUTPUT);
   }
void loop()
   {
        for ( int j= 2; j<11 ; j++)   // Va encendiendo los segmentos
           {
              digitalWrite(j, HIGH);
              delay(400) ;
           }
        for ( int j= 2; j<11 ; j++)   //Apaga todos los segmentos
              digitalWrite(j, LOW);
        delay(400) ;
   }

Opción 2 (Pasa automáticamente los números).

const int a = 2;
const int b = 3;
const int c = 4;
const int d = 5;
const int e = 6;
const int f = 7;
const int g = 8;
void setup() {
  pinMode(a, OUTPUT);
  pinMode(b, OUTPUT);
  pinMode(c, OUTPUT);
  pinMode(d, OUTPUT);
  pinMode(e, OUTPUT);
  pinMode(f, OUTPUT);
  pinMode(g, OUTPUT);
}
