Barcodes are designed for computers to read quickly by scanning red LED or laser light across them.Įach digit in a barcode is represented by seven equal-sized vertical blocks. S.N.Ī barcode represents the line of numbers printed underneath it with a pattern of black and white bars. You can purchase all the components online from Amazon. To design your own QR Barcode Scanner, we need following components. And finally, we will interface the Barcode + QR Code Scanner with Arduino Board and display the read data on OLED Display. Apart from this, we will be going through the details of the Maikrt Embedded QR Code Scanning Module. In this tutorial, we will learn what is QR & Barcode and how the technology works. It uses the intelligent image recognition algorithm to identify the Barcode and QR Code data. It is a small 1D/2D codes reader that can be embedded in any device for scanning code to identify other items. The module supports both USB and UART Serial communication. They are used in retail stores as part of the purchase process, in warehouses to track inventory, and on invoices to assist in accounting.įor making Arduino Barcode + QR Code Reader, we will use Maikrt Embedded QR Code Scanning Module. Similarly, Barcodes are applied to products as a means of quick identification. More recently, they have played a key role in helping to trace coronavirus exposure and slow the spread of the virus. QR codes are frequently used to track information about products in a supply chain, often used in marketing and advertising campaigns. You can also make a simple ESP32 CAM QR Scanner using the ESP32 Camera Module but it requires computer screen for visualization. The DIY QR & Barcode scanner can scan the Barcode or QR Code and display the read information on the OLED Display.
