This Auto Botix Smart Toll System is a fun DIY project kit that allows you to build a toll system for your toy cars. The system uses RFID tags on the toy cars to automatically detect when they pass through the toll gate and keeps count of total trips. Kids can have hours of imaginative play setting up toll roads and collecting fees. The kit comes ready to use with an RFID reader, tags for the cars, wiring and connectors to assemble the toll gate. An LCD screen displays the trip count in real-time. Simple instructions get you building in no time. It’s educational while sparking creativity. Great for developing problem-solving and engineering skills.
