El pin n\u00famero en este m\u00f3dulo se lo utiliza para encender o apagar el m\u00f3dulo gsm, por lo cual en este proyecto no lo vamos a usar porque no hay necesidad de apagar o encender el m\u00f3dulo.<\/p>\n<p>Lo pines usados para los led son el numero 4 5 6 8 9 10 11 12 y 13, tambi\u00e9n se pueden usar los pines A0 al A5 (pines anal\u00f3gicos) y en total podr\u00edamos controlar hasta 15 dispositivos a las vez.<\/p>\n<p>El m\u00f3dulo seg\u00fan el fabricante necesita una fuente que pueda entregar hasta dos amperes de corriente, para poder funcionar sin inconvenientes.
