+Programa que solicita telemetria al sistema embebido, por medio del comando  0xFe
+para preguntar por el color  que detecta el sensor TCS3200
+
+el sistema embebido recibe  el inicio de trama FE  y el número de comado: 01

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