Ciao a tutti, sono nuovo del mondoArduino e sto cercando di creare un termometro con 3 display 7 segmenti. Ho trovato in rete questo circuito:
sto cercando di adattarlo alle mie esigenze e con questo codice riesco a leggere solo le prime due cifre
questo e il codice che sto usando
#include <math.h>

pinMode(6, OUTPUT); // Segment F, Pin 2
pinMode(5, OUTPUT); // Segment A, Pin 10
pinMode(4, OUTPUT); // Segment E, Pin 4
pinMode(3, OUTPUT); // Display 3
pinMode(2, OUTPUT); // Display 2
pinMode(1, OUTPUT); // Display 1

C'e qualcuno che puo darmi una mano? con l'elettronica non ho grossi problemi ma con i codici abbastanza 
Grazie
Ciaooo
