The AutoUnlocker is an automated door unlocking system. It is designed to add convenience to the everyday task of unlocking a door that is designed to only be unlocked with a key. It saves time and effort by using a continuous servo motor to pull the door lock open from the inside when the user enters a passcode. A 3D printed mechanism made out of PLA easily slides over the door lock. The mechanism features a hole near the top to allow a string to be tied from it to the micro servo. When someone wants to unlock the door all they need to do is press the button and then enter the passcode. A green LED or red LED will blink to let the user know whether they were right or wrong respectively. When the passcode entered is incorrect, the door won’t be unlocked and the user is free to try again. If the code is correct, the micro servo will pull the door lock to its unlocked position and then rotate the opposite direction to release tension in the string so that the door can be locked again. The code can be easily edited and re uploaded to change the passcode for added security and customization.
