Chocolate vending machine using waste plastic bottles
The simplest way to reduce plastic waste is to avoid unnecessary and single-use plastics, support businesses that are reducing plastic waste and re-use existing plastic. Say no to disposable plastic cutlery, plastic straws and other single-use plastics. Avoid plastics that cannot be recycled if other alternatives exist. Here we have designed a model where we can get chocolates against plastic bottles. This is a model on chocolate vending machine using waste plastic bottles. The main objective of our project is to launch new technology application in society. This is Arduino based vending machine. This project attempt to provide solution in waste bottle based vending machine which is very useful for society to keep it clean.
Whenever any person tries to put the bottle into the machine, the machine detects the person using IR sensor and opens the cover of the machine. When he puts the bottle the machine again detects and give back chocolate to the person. Here Arduino is the heart the project. IR sensors are the input section and motor, buzzer is the output section.
