KEYPAD SOLENOID DOOR LOCK SYSTEM USING ARDUINO

 


In this Project lets learn how to build a Password based door lock system by interfacing Arduino with 4×4 Keypad to enter the passcode. We also connect an LCD display to make ease of entering passwords and changing the passwords without hardcoding Arduino again.  We are using a Solenoid lock which locks and unlocks the doors by entering the password through the keypad and LCD display is used to display the status and messages.

With this Project we can build a security system which works with password. In day today life everything is becoming simple and advanced, previously to lock something we used to have a padlocks, combination locks. But due to increase in thefts and technology, new type of locks such as electronic locks, smart locks were invented and people are using them widely to protect their assets.
