📸 QR Code Scanner Using ESP32-CAM 🖥️

This project showcases the creation of a QR code scanner using the ESP32-CAM module. Here ESP32-CAM captures images and sends them to a server with a QR code recognition program via an API request. Once the recognition is complete, the server responds with the decoded data. It's straightforward and with our QR Code Scanner API, the process is smooth and efficient.
