Blynk ESP32/ESP8266 Door Monitoring System

This is a simple door monitoring system using an ESP32/ESP8266 and Blynk app.

Requirements

• Arduino IDE
• ESP32 or ESP8266 board support for Arduino IDE
• Blynk app installed on your smartphone

Hardware

• ESP32/ESP8266 board
• Magnetic door switch
• Servo motor
• LEDs
• Resistors
• Wires
• Breadboard

Installation

1. Install the ESP32 board support for Arduino IDE. Follow these instructions.
2. Install the Blynk library for Arduino IDE. In the Arduino IDE, go to Sketch > Include Library > Manage Libraries, then search for "Blynk" and install it.
3. Download or clone this repository to your computer.
4. Open the esp32-door-monitoring-system.ino file in Arduino IDE.
5. Modify the following lines with your Wi-Fi and Blynk credentials in config.h file (and don't forget to create it too in same folder as config.h). :

your config file will be look like this:

#ifndef CONFIG_H
#define CONFIG_H

#define MY_ID "INSERT_TEMPLATE_ID_HERE"
#define MY_TEMPLATE_NAME "INSERT_TEMPLATE_NAME_HERE"
#define MY_AUTH_TOKEN "INSERT_AUTH_TOKEN_HERE"
#define MY_SSID "INSERT_WIFI_SSID_HERE"
#define MY_PASSWORD "INSERT_WIFI_PASSWORD_HERE"
#endif // CONFIG_H

6. Connect the hardware as shown in the diagram below.
7. Upload the code to your ESP32 board.
8. Open the Blynk app on your smartphone and create a new project.
9. Add the following widgets to your project:

• Slider widget on V3
• Button widget on V7

10. Set the properties of the widgets as follows:

• Slider widget on V3:
  • Output: Virtual Pin V3
  • Min value: 0
  • Max value: 180
• Button widget on V7:
  • Output: Virtual Pin V7
  • Mode: Switch
  • OFF value: 0
  • ON value: 1

11. Run the project and enjoy monitoring your door!
