Wifi door lock DIY by Arduino & ESP8266

This project will guide how to make WIFI door lock by your own with ESP8266, program by Arduino IDE
You can make it for your home. I hope you will like it, please leave comment

For anyone who want to change door password (default is 123456)
Search the code to "password_key == 654321" and change it, password will work by reversed direction (e.g. password 456789, then you should set it "password_key == 987654")

Sir, can keep a servo motor for the relay. Can you send the code for it?

When I upload the code, there is "Eror compiling for board NodeMCU 1.0 (ESP-12E Module)". Any solution for this problem?

[inikamil]

Excuse me sir, may I ask for the size design for the box?

Hi, nice project thank you! We will use another way to your lock system in our project. But I didn't understand that the password 123456 and also 654321 work and when we wants to close the lock red button doesn't work, we enter the pass and press the red button lock closed. Could you please help us? By the way, we refer to you in the project. :) ✌
