<\/iframe><\/p>\n<hr \/>\n<p>Es posible conectar un teclado PS\/2 a un Arduino sin la necesidad de una PC. Para hacerlo, necesitar\u00e1s un adaptador de teclado PS\/2 a TTL que puedes conseguir en tiendas de electr\u00f3nica.<\/p>\n<p>Luego, conecta los cables del adaptador a los pines correspondientes del Arduino, que son los pines digitales 2 y 3 para la se\u00f1al de reloj y de datos, respectivamente.<\/p>\n<p>Una vez conectado el teclado al adaptador y el adaptador al Arduino, deber\u00e1s cargar un programa en el Arduino que permita leer los datos del teclado y mostrarlos en el terminal serial.<\/p>\n<p>Existen diferentes bibliotecas de software disponibles para leer los datos del teclado PS\/2 en un Arduino, como la biblioteca “Ps2KeyboardHost” que puedes encontrar en el administrador de bibliotecas del Arduino IDE.<\/p>\n<p>Con la biblioteca adecuada y el c\u00f3digo de programaci\u00f3n correcto, podr\u00e1s leer los datos del teclado y utilizarlos para controlar otros dispositivos o ejecutar acciones en el Arduino sin necesidad de una PC.<\/p>\n<hr \/>\n<p
