<\/iframe><\/p>\n<hr \/>\n<p>Segunda parte del teclado para PC, con arduino micro, pero que ahora agrega algunas mejoras significativas, ya que agrega un m\u00f3dulo bluetooth para conectarnos a una aplicaci\u00f3n para celular, con app inventor, y de esa manera agregar un teclado virtual con nuevas funciones. Tambi\u00e9n se le agrega un display oled, para ver cual fue la \u00faltima tecla presionada, y un buzzer que nos avisar\u00e1 cuando una secuencia de teclas haya finalizado. Analizaremos el c\u00f3digo fuente, la aplicaci\u00f3n en app inventor y finalmente probaremos el funcionamiento del mismo.<\/p>\n<hr \/>\n<p style=\"text-align: left;\">Tal vez pueda interesarte
