Reverse Vending Machine For Exchange Empty Containers To Money

In the Reverse Vending Machine (RVM) tool, there are factors that affect the accuracy of the sensor, namely environmental and human factors, both from the environment, namely air and light that can interfere with the sensor. And humans who from the way put containers into the tool. The sensor will not function properly there is interference in practice. So a scan place is made by trying to overcome these problems which reduce environmental disturbances and help users to enter the container properly. This system uses Arduino UNO as a microcontroller and several sensors to perform scanning, conveyor and dynamo motors as drives, linear aquators as presses, and servo motors as coin thrusters. This system aims to sort containers in the form of plastic bottles and cans from other containers and after pressing they are separated again in storage. There are differences in the data obtained from sensors and other tools. The sensor difference is quite small but does not affect the overall performance of the tool. Because when a scanning error occurs, the container will be issued and given to the user. But there are cases of error items getting into storage, and those cases are very rare.
