+/*********
+Este archivo es una modificacion al ejercicio propuesta por el ingeniero Ferney alberto Beltran
+molina.
+generar un programa que controle por el puerto serial el grado de 4 servo motores.
+por medio de la comunicacion serial el comando es

+
+
+para enviar los comandos usar el programa Coolterm http://freeware.the-meiers.org/

+# width = 1000us y 2000us
