Ciao a tutti, mi sto cimentando nella costruzione di una replica giocattolo di ordigno a tempo.
E' composta così:
Arduino 2009 (poi implementerò un mega 2560)
LCD 20x4 parallelo color blu
keypad 4x4
Il software dovrebbe far sì che prima viene richiesto il codice, la bomba si arma, parte il timer e nel mentre si dovrebbe riuscire ad immettere un codice di disinnesco. Detto ciò non riesco assolutamente a far apparire il timer che faccia il conto alla rovescia!!!
Ho provato in tutte le maniere ma faccio solo dei pasticci, ormai è quasi 3 settimane che litigo con il libro di arduino e il mio cervello, mi date una mano per favore?
ecco il codice
//#include <Event.h>
#include <Timer.h>
#include <Keypad.h>
#include <LiquidCrystal.h>
#include <Tone.h>
#define pound = 14
Tone tone1;
int Scount = 0; // count seconds
int Mcount = 0; // count minutes
int Hcount = 0; // count hours
int Dcount = 0; // count days
int val = 0;
long secMillis = 0; // store last time for second
long interval = 1000; // interval for seconds
char password[4];
int currentLength = 0;
int i = 0;
char entered[4];
LiquidCrystal lcd(12, 13, 11, 10, 9, 8);
const byte ROWS = 4; //four rows
const byte COLS = 4; //three columns
char keys[ROWS][COLS] = {
{
'1','2','3','A' }
,
{
'4','5','6','B' }
,
{
'7','8','9','C' }
,
{
'*','0','#','D' }
};
byte rowPins[ROWS] = {
3, 2, 1, 0}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {
7, 6, 5, 4}; //connect to the column pinouts of the keypad
Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
