Despite it, people still inclined to overlook the fact that the aluminum scrap thrown away is recyclable and beneficial. The authors have therefore set up a machine which will represent as a recycling bin. Through problem identification, the objectives were identified as guides in the establishment of “Aluminum Can to WiFi Trading System with Metal Can and Plastic Bottle Collector and Monitoring System” for the school. This machine is designed to have a ramp and dimension that serves as the pathway of the collected metal cans and plastic bottles and houses a bin designated for each material. It is equipped with ultrasonic, inductive, and infrared sensors to sort, monitor, and count the metal cans and plastic bottles. It displays information, terms and condition, and transaction through the TFT LCD screen with three pushbuttons as its user input. It was installed with an Access Point that serves as the Network Address Translator to provide internet access to the user. This document proposes a project based on a microcontroller, with microelectronics devices namely, Ultrasonic Sensor (HCSR04), TFT LCD Display (MD070SD), IR proximity sensor, NPN Inductive Sensor LJ12A3-4-Z/BX NPN, an MG996R Servo and SG90 Micro Servo, ESP8266 node MCU, Arduino MEGA and push button. These have been programmed carefully and patiently tested to ensure its working conditions. The authors came up with an aluminum trading device in a robotic application with features such as access point, monitoring device, and sorting of metal cans and plastic bottles through well-planned design, data gathering, and reliability testing. The writers proved that the system is favorable and will support the school in managing the plastic bottles and metal cans used by the students.
