![]() ![]() If a match is found, the tag is considered valid.īarrier Control: Upon successful tag validation, the Arduino activates the micro servos, causing the barrier arm to open. Tag Validation: When a tag approaches the toll barrier and the RFID module detects an RFID tag, it reads the unique ID from the tag.ĭatabase Lookup: The Arduino then checks the received RFID tag ID against the registered tags stored in its database. RFID Tag Detection: The system constantly monitors the RFID reader for any RFID tags in its range. Initialization: When the system is powered on, the Arduino initializes the RFID module, OLED display, and micro servos. The RFID tag is associated with the users account. RFID Tag Registration: Before using the system, each user must register their RFID tag in the system's database (arduino). This works similarly to the actual toll system, the only change here is instead of the money/credits we are just using the access permission for eligible tag users.Īlso, we don't use any cloud storage, the rest of the things remain the same, to make it easily understandable I will explain taking account of individual functions in a system I wanted to make things easily understandable for any average student, so I came up with a working model that would demonstrate the working as similar to a real toll tax system instead of barely explaining theoretically. The sole purpose was to spread the knowledge of toll tax system, you might have seen them in daily life if you live in urban areas but have you really thought about how these really work? ![]() To begin with, let me go through the purpose of this project Note that since it's a valuable project(considering students) I will be explaining things in depth, so buckle up to get educated on the things that you might not heard of before( this statement is for beginners only!!) ![]() With the help of my step-by-step instructions, Circuit diagram, and codes you can build this project with ease. If you are seeking a mini project for high school or engineering junior I would highly recommend you to try this project. Hi readers, in this instructables i have come up with some interesting project! Yes, This is an Arduino-based RFID-powered toll tax barrier system with an OLED display. ![]()
