WIFI Door Lock DIY

Make wifi door lock by yourself, open/close door lock by Phone. This project is based on ESP8266

Step 1: Part List

1. Node MCU Ver 0.9

2. Solenoid lock

3. H-bridge

Step 2: Code Work

Here is the code: https://bit.ly/3ylwNE9

Step 3: Test Run

After compile and download the code, ESP8266 will be a Wifi station (Access Point).

Now you can use smart phone to connect to wifi station named Engineer2you-Home with password is "123456789" (Of-course you can edit the name and password in Arduino code)

After connection successful, go to web browser on phone and type address 72.72.72.72 (again, you can also edit this address in Arduino code). The web screen of lock status will appeared!
Press "door button" |]||[ : if lock is opened, it will close the lock (without password) Input password to open the lock: password is "123456", ofcourse you can change this password in Arduino code. If wrong password, you can not open the lock.

Step 4: Make Circuit and Installation

I made small home model, then install solenoid lock, "WIFI LOCK" controller box, then test again. It works fine!

Then I print QR-Code for address 72.72.72.72 and stick on door. Imagine that, you get home, use the phone to scan QR-Code and input password to open the door, so cool! haha
