(Last Updated On: July 17, 2019)

Bluetooth smart lock

Description:

This is a very detailed tutorial on how to use the hc-05 and hc-06 Bluetooth module to make the smart lock. In this tutorial, you will also learn how to change the name of the Bluetooth module and how to change its pin code or pairing code using AT commands. With the help of this project, the Electronic lock can only be controlled by the authorized person having the cell phone Application.

For more details and step by step explanation watch video Tutorial given at the end of this Article.
