Automatic Car Scanner (First Look Prototype)

This is a first look at a new, working Automatic Car Scanner for Model Railroads. It is low cost, self contained, and capable of sending train car lists to HTML Web Pages, paper via serial port, local OLED Displays, and JMRI (via an MQTT Broker). It scans small QR Code labels that you can print with a wide variety of messages or information. A detailed article concerning its complete construction can be found on the Model Railroad Hobbyist site: https://forum.mrhmag.com/post/sma48-working-automatic-car-identification-aci-for-model-railroaders-13446525?trail=25
