ESP32 Interrupt HTTP Client

An ESP32/Arduino sketch that uses a GPIO-change interrupt to fire off an HTTP GET reporting a device status to your server.

🔧 Features

• Interrupt-driven HTTP GET on pin change
• Easy configuration of WiFi credentials, device ID & server URL
• Built with the Arduino-ESP32 core and HTTPClient

⚙️ Prerequisites

• ESP32 development board
• Arduino IDE (https://www.arduino.cc/en/software) with “ESP32 by Espressif” support installed
• A server endpoint ready to accept GET requests

🔌 Wiring

• GPIO 13 → your sensor or switch (pulled up internally)
• ESP32 GND → sensor GND

🚀 Usage

1. Clone this repo.
2. Open sensor_interrupt_client.ino in Arduino IDE.
3. Configure pins, WiFi, URL.
4. Upload to your ESP32.
5. Flip your sensor/switch → check Serial Monitor for HTTP response.
