Welcome to the ESP32 Google PubSub project! 🎉 This repository is a continuation of the ESP32 JWT Auth project, where we integrate Google Pub/Sub with the ESP32 microcontroller for efficient messaging and event-driven architectures.
This project demonstrates how to use Google Cloud Pub/Sub with the ESP32 microcontroller, allowing for seamless communication between IoT devices and cloud services. ☁️ It leverages JSON Web Tokens (JWT) for secure authentication and authorization. 🔒
- Secure Communication: Utilize JWT for authentication with Google Cloud services. 🔐
- Real-time Messaging: Publish and subscribe to messages in real-time using Google Pub/Sub. 📬
- IoT Integration: Connect your ESP32 devices to the cloud for scalable IoT solutions. 🌍
