Enviar mensaje a arduino con twitter

En este laboratorio vamos a enviar mensajes de twitter para que arduino haga lo que deceemos en este caso voy a ecender el color de led que quiero, todos o efecto lampara. con solo darle (averde, erojo, eazul, averde, aazul, arojo, etodos, atodos, elampara o alampara). y arduino recoje la informacion que envie desde mi twitter.



herramientas:

1 arduino uno
