Aqu\u00ed tenemos una maqueta de ascensor hecha con Arduino Nano que incluye una pantalla LCD y un teclado matricial para realizar las configuraciones y pr\u00e1cticas necesarias. Como pueden ver, subimos al segundo nivel… y al tercer nivel…<\/p>\n

Esta maqueta se dise\u00f1\u00f3 con la finalidad de hacer pr\u00e1cticas y experimentar con el funcionamiento de un ascensor real. Dado que la tarjeta de control utiliza un microcontrolador Arduino Nano, a trav\u00e9s de este puerto USB tipo C podemos cargar el programa y al mismo tiempo nos sirve de alimentaci\u00f3n. Pr\u00e1cticamente es como tener un circuito en un protoboard con una tarjeta Arduino Nano, con la diferencia de que todo est\u00e1 integrado en esta tarjeta compacta.<\/p>\n

\u00bfTe gustar\u00eda saber c\u00f3mo se desarroll\u00f3 este proyecto desde cero? Desde el dise\u00f1o del esquem\u00e1tico electr\u00f3nico, el dise\u00f1o de la tarjeta PCB hasta el armado de la estructura completa. Pues no te despegues de este art\u00edculo.<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n<\/div><\/div><\/div><\/div><\/div><\/section>
