In this video, we will learn how to make our own Barcode + QR Code Reader using Arduino & Embedded QR/Barcode Scanner Module. The DIY QR & Barcode scanner can scan the barcode or QR Code and display the read information on the OLED Display. You can also make a simple ESP32 CAM QR Scanner using the ESP32 Camera Module but it requires a computer screen for visualization.

QR codes are frequently used to track information about products in a supply chain, often used in marketing and advertising campaigns. More recently, they have played a key role in helping to trace coronavirus exposure and slow the spread of the virus. Similarly, Barcodes are applied to products as a means of quick identification. They are used in retail stores as part of the purchase process, in warehouses to track inventory, and on invoices to assist in accounting.

For making Arduino Barcode + QR Code Reader, we will use Maikrt Embedded QR Code Scanning Module. The module supports both USB and UART Serial communication. It is a small 1D/2D codes reader that can be embedded in any device for scanning code to identify other items. It uses the intelligent image recognition algorithm to identify the Barcode and QR Code data.

In this tutorial, we will learn what is QR & Barcode and how the technology works. Apart from this, we will be going through the details of the Maikrt Embedded QR Code Scanning Module. And finally, we will interface the Barcode + QR Code Scanner with Arduino Board and display the read data on OLED Display.
