I am work on an RTC with arduino uno and LCDKeypad shield, when i compile the code it gives this error
< fatal error: LCDKeypad.h: No such file or directory
compilation terminated.
Error compiling.>
This is the code
<< #include <LiquidCrystal.h>
#include "Keypad.h"
#include "Wire.h"
#define DS3231_I2C_ADDRESS 0x68
#define DAYS 0
#define HOURS 1
#define MINUTES 2
#define SECONDS 3
// The LCD screen
LCDKeypad lcd;
// The time model
unsigned int days = 0;
unsigned int hours = 0;
unsigned int minutes = 0;
unsigned int seconds = 0;
unsigned int setting = 0;
void setup() {
// Set up the LCD's number of columns and rows:
lcd.begin(16,2);
// Set the cursor at the begining of the first row
lcd.setCursor(0,0);
// Print a text in the first row
lcd.print("Setting: Days ");
}
void loop() {
// Increase the time model by one second
incTime();
// Print the time on the LCD
printTime();
// Listen for buttons for 1 second
buttonListen();
}
void buttonListen() {
// Read the buttons five times in a second
for (int i = 0; i < 5; i++) {
// Read the buttons value
int button = lcd.button();
switch (button) {
// Right button was pushed
case KEYPAD_RIGHT:
setting++;
break;
// Left button was pushed
case KEYPAD_LEFT:

break;

days++;
break;

}
