Hi there, I read your requirements carefully. I can help upgrade your automatic dustbin prototype so it works with an RC522 RFID wristband, Arduino Nano, LED status, and six-credit activation logic. My approach will be to remove/bypass the stock IR trigger, wire the RC522 reader to the Nano, connect the dual-colour LED, and control the existing lid actuator/servo so the lid opens on an authorized tap, waits 3 seconds, then closes again. I’ll also add debounce logic so repeated scans from one tap do not consume multiple credits. I can write clean Arduino code for: Authorized wristband detection 6 credits per wristband Green LED when credits remain Red LED after credits are used One tap = one activation Servo/actuator open-close control Simple serial/debug output for testing I have experience with Arduino, RFID modules, sensors, LEDs, basic circuit wiring, and embedded prototype logic. I’ll make the setup neat, easy to test, and understandable for future upgrades like wireless logging or pump control. Cost: ₹2,000 || Timeline: 1 day after receiving parts Payment and timeline details can be discussed further to align with your expectations. Best regards, Oluwatobi Okedairo

Hi, I have prior hands-on experience working with RFID-based embedded systems, including developing an automatic ration machine project that involved RFID authentication, controlled access logic, and real hardware implementation. Because of this, I already understand the practical integration of RFID modules, user validation, and actuator-based automation systems, which makes me a strong fit for this project. Your food cart dispenser concept is practical and aligns well with my experience in: Arduino/ESP32 embedded systems RFID integration (RC522) Sensor and actuator control Prototype hardware development Functional product system design I can help you: Replace the stock IR module with RC522 integration Develop reliable Arduino Nano firmware for wristband authentication and 6-credit logic Implement proper tap debouncing for accurate credit deduction Integrate LED status indicators Ensure stable actuator control for real-world bench testing My background combines both embedded systems and product development, allowing me to approach this as a complete working prototype rather than only a coding task. Estimated turnaround: 3-7 days, depending on hardware inspection and testing. I’d be happy to discuss the dustbin’s internal control setup and suggest the most reliable implementation approach.

Hello, your RFID dispenser prototype needs someone who can seamlessly integrate the RC522 reader and I have hands-on experience doing just that. I am Mubashir, a Full-Stack Developer with 6+ years building embedded systems and Arduino projects. I understand that your main focus is on replacing the existing IR sensor with the RC522 RFID reader to ensure a smooth operation with the wristbands. 1. First, I will remove the stock IR proximity module from the dustbin’s control board and securely position the RC522 reader in its place. 2. Then, I will wire the reader to an Arduino Nano along with a dual-colour LED to indicate credit status. 3. After that, I will write clean and well-commented Arduino code to recognize authorized wristbands, limit lid activations to six per band, and manage the servo/actuator for the lid operations. 4. Finally, I will thoroughly test the setup on your bench to ensure reliable performance and demonstrate its functionality. Even if you're not ready to move forward, I can provide a FREE detailed quotation and project proposal with a suggested roadmap. This way, you’ll have a solid reference document whether you decide to work with me or someone else. >>> My Work: https://www.freelancer.com/u/mubashir021 <<< Drop me a message and let's get this sorted.
