Hola
Siempre intento poner atención a todo lo que me piden, soy novato en esto sólo quiero construir un goto para el telescopio ( el oficial me sale por 400€...)
Si prestases atención a lo que puse al principio te darías cuenta ( eeeh, sólo bromeo 
) de que no me da error, he subido el Scketch al arduino, pero al probar los comandos en el monitor serial no me contesta como se supone que debería hacerlo , por ejemplo escribo CONNECT# y debería contestarme OK#, pero se queda en blanco.Al final te mando un pantallazo par que veas lo que me sale a veces un cuadrado y un signo de interrogación.
Gracias!
