The process of supply is defined as the distribution or delivery of one or more products to a worker, with the respective control and registration of what enters and leaves the storage. This document describes the process of building a prototype vender machine for packets and/or medical supplies. The structure of the machine, is formed mainly by iron angles, which have been welded; the gutters containing the packets are suspended by a grid of wooden boards. The displacement of the head that pushes and throws the packages, is executed through the Core XY system. Unlike most of this type of machines, it doesn’t work with stepper motors but with DC motors, which are controlled from a Raspberry pi 3 embedded system and an L-298N driver. To supply the dispenser and to remove the products, a fingerprint sensor is used and as a security measure, the door through which the packets are stored, is controlled by a 180-pound electromagnet. This machine was developed for the grocery store "El portal de Andrea", located in Tuluá city, Valle del Cauca. This work is the final result of the application of all knowledge acquired during the study of the Electronic Engineering, attached to the Faculty of Engineering of the Unidad Central del Valle del Cauca, and the advice of the same University's professors.
