This barcode reader system uses an Arduino development board to decode barcode data and display it on a 16×2 LCD screen. A barcode reader module scans barcodes and sends the data to the Arduino via serial communication. The Arduino processes and displays the scanned code, making the system useful for testing and troubleshooting barcode-based applications.
