Hi guys, I would like to add a delay to this:
if(!strcmp(Data, Master)) // equal to (strcmp(Data, Master) == 0)
lcd.print("Letter: D");
else
When I do however i get:
exit status 1
expected ‘}’ before ‘else’
It makes sense to me that i’m not missing anything here. Can someone help?
Full Code:
#include <Keypad.h>
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
#define Password_Lenght 4 // Give enough room for six chars + NULL char
#define GPIO_ADDR 0x27
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // set the LCD I2C address
char Data[Password_Lenght]; // 6 is the number of chars it can hold + the null char = 7
char Master[Password_Lenght] = "145";
char Master2[Password_Lenght] = "124";
char Master3[Password_Lenght] = "125";
char Master4[Password_Lenght] = "245";
