Help on password

Projects Programming
1

Hello. So i wanted to try the passwork with keypad example and i added something new to the code but it doesnt seem to work. (the rest of the code is the same with the example )

void checkPassword(){
  if (password.evaluate()&&digitalRead(12)==HIGH&&digitalRead(11)==HIGH){
    Serial.println("Success");
    digitalWrite(13, HIGH);

The 12 and 11 are aleph magnetic contacts.So basically i want the led(13) to turn on when both the contacts are HIGH and the password is correct. Can someone tell me why isnt this working?

What is "password.evaluate"?

(the rest of the code is the same with the example )

Wuh?

Wuh?

I dont understand what you mean. If you mean what is the correct password it is 1234

You can help us by showing the wiring, or you can debug this yourself by using Serial.println to print the values of digitalRead(11), digitalRead(12), and password.evaluate().

How are pins 11 and 13 connected?

What happens when you tie them high?

a magnetic contact is connected to pin 11 and ground(like the magnetic contact at 12) and a led is connected to pin 13 and ground. When the magnetic contact is HIGH it means that the electromagnet and the magnet are touching each other. And the led when it is HIGH it emmits light. Even though they are touching one another the led still doesnt turn on.

Aleph magnetic contact. I cant explain it but if you google it im sure you can find out what it is. It is used in security systems

What does your multi-meter measure on these pins?

Your comment made me figure out what i should have done. On void setup i should have put pin 12 and pin 11 to HIGH. So now its all good thanks all of you for your time
