Project Description:
********************
In today’s episode, you will learn how to make the most efficient Password protected door lock security system using Arduino and a keypad. When you enter the correct 4 digit password the door is opened for 5 seconds…Currently, the password is 1234, which you can change in the programming, you can even select a password consisting of more than 8 digits. I have checked this Password Door Lock Security System many times and it worked perfectly…If a wrong password is entered 3 times the person is locked out for 5 seconds and an led is turned ON, which can be replaced with a buzzer. The number of wrong attempts can be increased or decreased as per the requirement…

In this episode, we will cover
1. 4x4 keypad Pinout
2. How the electronic lock works
3. Complete circuit diagram
4. Arduino programming and finally
5. Testing
