Buenos dias, Inicialmente me gustaria agradecer a toda esta maravillosa comunidad por su gentileza al momento de compartir ideas y ayudar a otros y expresarles mi mas sincero agradecimiento.
El problema es el siguiente, estoy intentando experimentar sobre la creacion de un pequeño sistema domotico con control de acceso, he copiado un codigo desde internet, Anexo link del autor y he intentado reproducirlo, ya he adicionado la libreria externa WEBDUINO, sin embargo al momento de verificar el codigo el copilador me indica errores, seria de gran ayuda entender cual seria el problema ya que no soy muy experto en tramas de comunicacion HTTP ni del lengauje
