Autopower vending machine controller

Abstract

Basically, this project is about a design of a controller for Autopower Vending Machine. For some reason, this design is needed as people are facing difficulties to use hand phones when battery is in low battery condition status. Now, here is the solution. The controller work as controlling the multiple output current using limit switch and push buttons. The process of charging will cutoff automatically once the currency which means the counter limit is finish decrement is finished. The machine will automatically start up when customer is near, and when there is no customer, the machine is power saving mode, which the controller cannot function at all and it means the system will stop after finish charging process. The programming for the controller is using C programming language in Arduino Uno board with own design of Input or Output ports. Result shows the functionality of the Autopower Vending Machine Controller for every part with detailed description which consist of 3 parts, input part, output part and charging circuit part. In a nutshell, the idea of this project will make people easier on getting hand phones in good battery condition with just a few coins in environmental friendly way.
