Abstract
This paper proposes the design and construction of a didactic vending machine, students pretend to be immersed in a work with delivery date as many companies that work for projects do. The project of vending machine to be developed will have as parameters that dispatch four different products, with a control panel, a 16 x 2 LCD screen which shows the cost of the chosen product or product, will have to give change and its data processing is via Arduino, a 3D simulation is carried out to ensure the compatibility of all components, an innovation presented by the prototype to be developed is that it sends a text message when a product is about to run out, with the product description, the number of machine and its location, this provides the supplier with better control over their large-scale machines. A comprehensive financial investment analysis is performed to ensure the viability of the project.
