ESP32 Wi-Fi Setup and Feedback Submission to API (Arduino Framework)

This project demonstrates using an ESP32 to set up Wi-Fi credentials through a web interface and send client-specific product quality feedback to a Zoho CRM API. The system utilizes a debounce mechanism to ensure reliable button-press detection for submitting feedback.

Features

• Wi-Fi Configuration: Configure Wi-Fi credentials via a hosted web interface.
• Button Press Feedback: Send feedback to an API when buttons are pressed.
• Debounce Mechanism: Prevent multiple detections for a single button press.
• SPIFFS: Used for internal storage.

How It Works

1. Wi-Fi Setup:

   • The ESP32 starts as a Wi-Fi access point named ESP32-Setup.
   • A hosted webpage allows users to input Wi-Fi credentials.

2. Button Feedback:

   • Monitors three buttons connected to GPIO pins.
   • Sends button feedback as a JSON payload to the configured API endpoint.

3. Debounce Mechanism:

   • Ensures only one signal is sent per button press.

4. API Integration:

   • Button states are sent as JSON to the specified API URL.
