Hi all, did anyone know how to call another function inside void loop function? My code as below:
Error: 'openDoor' was not declared in this scope
#include <Servo.h>
#include <Keypad.h>
#include <EEPROM.h>

{'1', '2', '3'},
{'4', '5', '6'},
{'7', '8', '9'},
{'*', '0', '#'}
};
char keypressed; //Where the keys are stored it changes very often
char code[]= {'6','6','0','1'}; //The default code, you can change it or make it a 'n' digits one
char code_buff1[sizeof(code)]; //Where the new key is stored
char code_buff2[sizeof(code)]; //Where the new key is stored again so it's compared to the previous one
short a=0,i=0,s=0,j=0; //Variables used later
byte rowPins[numRows] = {8,7,6,5}; //Rows 0 to 3 //if you modify your pins you should modify this too
