Display 16 segmenti comandato con Arduino e TLC5940
Il programma accende, sul display, in sequenza i numeri da 0 a 9. Nella matrice md con 10 righe e 16 colonne ci sono i valori 1 (acceso) e 0 (spento) che determinano quali segmenti, collegati alle 16 (0-15) uscite del TLC5940 secondo lo schema dell'immagine sopra, vanno accesi per ottenere, sul display, i numeri da 0 a 9.
