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.

[Note: As this projects are very simple we are only providing the code, schemaitic, and a few essential images if you want to get the images or code explanations do check out the Circuit Digest ...
