Hoy les mostrar\u00e9 una maqueta de un panel de precios para gasolineras. En este panel, podemos ver el precio del Diesel, luego los precios de la Gasolina 95, 90 y 84. M\u00e1s abajo tenemos una pantalla con tres pulsadores, que nos permiten configurar los precios de manera f\u00e1cil. Para demostrar c\u00f3mo funciona, haremos un ejemplo cambiando el precio de la Gasolina de\u00a0 84.<\/p>\n

Al iniciar, la pantalla solicita una clave de acceso. Una vez ingresada correctamente, podemos navegar por el men\u00fa principal para modificar los precios. Bajamos hasta la opci\u00f3n de la Gasolina 84 y ajustamos el precio. Mientras lo hacemos, el cambio tambi\u00e9n se refleja en el display principal. Este proyecto est\u00e1 construido con un ESP32 y programado en el IDE de Arduino. A lo largo del video, les explicar\u00e9 el esquem\u00e1tico electr\u00f3nico, el dise\u00f1o de la PCB y la estructura del panel.<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n<\/div><\/div><\/div><\/div><\/div><\/section>
