Abstract: This project is a smart and eco-friendly system designed to encourage people to recycle plastic bottles. The idea is simple: when a person adds a plastic bottle to the machine, the system checks the bottle using a small electronic tag (called an RFID tag) that is attached to it. If the bottle is valid, the system accepts it and gives some cash to the user as a reward. At the heart of this system is the Arduino Mega, a mini-computer that controls everything. It connects and manages all the parts of the system. The user interacts with the machine using a 2.4-inch touch screen display. This colorful screen shows instructions like “Please insert the bottle” or “Scan complete” and even has buttons that the user can touch to start or finish the process. When the bottle is inserted, an RFID Reader (RC522) scans the RFID tag on the bottle to identify it. If the tag matches the system’s records, it sends a signal to the machine to move the bottle using a servo motor (MG90S). This small motor carefully rotates to pull the bottle inside the system. Once the bottle is accepted, the system activates a cash dispenser to give a small amount of money to the user. This makes the experience rewarding and motivates people to return plastic bottles instead of throwing them away. All the electronic parts are connected using a Printed Circuit Board (PCB) and jumper wires, which help the system work smoothly and keep everything organized. This smart recycling machine can be placed in public places like schools, malls, or parks to reduce plastic waste and promote recycling. It’s a small step toward building a cleaner, greener, and smarter world.
