You can Open or Close a lock using keypad with the help of Arduino. All you need is an Arduino, servo motor and Keypad. In this video, we are going to show you how to make an arduino project for home automation to open or close door using a password. Write a program to take input from keypad and open or close the door based on the password received from smartphone. Let’s look at the required components:

u did’nt shared the source code and without it your project will go in vain.
which one you shared in Youtube is not working (uploading error).
please give me the modified one which one is workable .
mail me at shakhawat.eu@gmail.com
thanks
Can i get the source code plz
did u get the code
Can i get the source code please ?
Where’s the code?
Please
#include
#include
#include
Servo servo1;
Password password = Password( “3262” );
const byte ROWS = 4;
const byte COLS = 4;
char keys [ROWS][COLS] = {
{‘1’, ‘2’, ‘3’, ‘A’},
{‘4’, ‘5’, ‘6’, ‘B’},
{‘7’, ‘8’, ‘9’, ‘C’},
{‘*’, ‘0’, ‘#’, ‘D’}
};
byte rowPins [ROWS] = {3, 2, A1, A2 };
byte colPins [COLS] = {7, 6, 5, 4};
Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS);
void setup() {
Serial.begin(9600);
servo1.attach(9);
keypad.addEventListener (keypadEvent);
}
void loop() {
keypad.getKey();
}
void keypadEvent (KeypadEvent eKey) {
switch (keypad.getState()){
case PRESSED:
switch (eKey) {
case ‘*’: checkPassword(); break;
case ‘1’: password.reset();servo1.write(90);break;
default: password.append(eKey);
}
}
}
void checkPassword(){
if (password.evaluate()){
servo1.write(180);
} else {
servo1.write(90);
}
}
I copied the code, and pasted it as you wrote above. but get the error message stray342 in program
code don´t work error message at line ” case ‘1’: password.reset();servo1.write(90);break;”
stray 342 in program
