RFID Dispenser Prototype Upgrade

I’ve built an early-stage food cart concept and now need the automatic dustbin I’m using as a mock dispenser to respond to an RFID wristband instead of its factory IR sensor. Your main focus will be integrating the RC522 RFID reader so a simple tap from a pre-tagged wristband opens the lid, deducts one credit, shows status with an LED, and closes the lid again after three seconds.

Scope of work
• Remove the stock IR proximity module from the dustbin’s control board and neatly position the RC522 reader in its place.
• Wire the reader to an Arduino Nano, plus a dual-colour LED (green when at least one credit remains, red once all six credits are consumed).
• Write clean, well-commented Arduino code that:
– recognises authorised wristbands,
– allows exactly six lid activations per band, then disables further taps,
– triggers the servo/actuator to open, waits three seconds, then closes,
– debounces multiple reads so one tap equals one credit.
• Demonstrate the finished unit running reliably on my bench.

I will supply the dustbin, RC522, Nano, LEDs, breadboard or jumper wires, and of course wristbands for testing. You may bring extra tools or headers if you prefer.

Why this is worth your time
• Perfect hands-on project for an ECE student—small budget but real hardware integration you can add to your portfolio or final-year demo.
• If the pilot works, there’s scope for further paid iterations (wireless logging, motorised pumps, hygienic housings, etc.).

Payment is ₹1,500–₹2,000 upon a working hand-off. We can meet locally to hand over parts, or ship if needed. Message me with your estimated turnaround and any previous Arduino or RFID work you’ve done, and we’ll schedule a quick call to confirm details.
