Mais étant novice en programmation je ne sait pas du tout comment mi prendre. J'ai trouvé ce code :
- Code: Tout sélectionner
/*
A set of custom made large numbers for a 16x2 LCD using the
LiquidCrystal librabry. Works with displays compatible with the
Hitachi HD44780 driver.
The Cuicuit:
LCD RS pin to D12
LCD Enable pin to D11
LCD D4 pin to D5
LCD D5 pin to D4
LCD D6 pin to D3
LCD D7 pin to D2
LCD Vee tied to a pot to control brightness
LCD Vss and R/W tied to ground
LCD Vcc to +5V
LCD pin 15 tied to pushbutton for control of backlight
This code has the custum numbers counting from 0 to 9 on
the left hand side of the LCD with a 1 sec delay between
numbers. On the right is a counter tracking the number of
times the program has looped.

mais si j'ai bien compris la boucle c'est pas un capteur qui détermine le chiffre à afficher mais le programme et moi je voudrai un programme qui puisse grâce aux données d'un capteur m'afficher mon nombre ( qui sera composé de deux chiffres ) sur l'écran.
J'espère avoir été clair et vous remercie d'avance de vos réponse.
