Recycle vending machine reverse tora / Maizatul Jannah Shahalan and Nur Erna Adrina Mustari

The idea of this project is to encourage people to recycle wastes by giving them monetary incentive. A recycle vending machine had been proposed. This recycle vending machine is one of the solutions to encourage people with recycling habits. The project is focus in recycling the aluminum can. Moreover, it helps to reduce the percentage of pollution. Pollution is one of the issues that received a great concern as the effects of the pollution are very worrisome. This project had everyone agreed as it is not just beneficial but also is very convenient and easy to use for everyone. The given name for this recycle vending machine is Reverse Tora. To make this vending machine works, we use Arduino Mega 2560 as it is a micro controller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the micro controller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. For the output, this machine requires the user to push the button to open the door. After the door open, the user will put the tins on the conveyor and the metal sensor will sense the tins. Next, the tins will be dropped into the box and user then will receive token based on the amount of tins that they recycle. Moreover, the user will listen to a short music as the appreciation for the user to recycle. For the output of this vending machine, this machine allows people to recycle tins as we use inductive proximity sensor which will sense only metal. After the user put a tin in the machine, the proximity sensor will sense the tin which allow the servo motor to open the lid and drop the tin. Next, ultrasonic will detect the presence of the tin and allows another servo motor at coin pusher section to push the token as the reward for user. After the user gets the token, led red, yellow and green will light up and buzzer will produce a melody sound.
