Controlling the access to your door remotely

In this recipe, we are going to learn how to open and close a door lock remotely, from anywhere in the world. You will then also be able to share this access with other people, so they too can gain access to this door lock.

Getting ready

For this project, we are going to use an actual electronic door lock that can be controlled from the Arduino board to lock/unlock a door. The component uses 12V as the power supply, so we are going to require an external power supply and some additional components to make it work.

This is the list of required components for this project:

• Electronic door lock (https://www.adafruit.com/products/1512)
• 1K Ohm resistor (https://www.sparkfun.com/products/8980)
• Rectifier diode ( ...
