Schematics

The circuit of the hidden lock

The image of the circuit contains an XMC2Go board, but you'll have to use a 3D Magnetic Sensor 2Go. They are very similar boards and they have the same pinout, however by default, XMC2Go doesn't have a 3D magnetic sensor.

Code

My code for the Hidden lock for smart houses project

This is the code that you need to upload to the board to replicate my project.

Library for the sensor

This library is required to use the magnetic sensor of the board. Follow the instructions of the repo to configure the Arduino IDE for the 3D Magnetic Sensor 2Go board

Home Manager

The door_lock folder contains the code for the ESP8266 if you want to use it
