  2.  * Para renomear conecte o bluetooth ao arduino ligando os pinos:
  3.  *
  4.  * En -> Pino 9 do arduino
  5.  * VCC -> +5Vcc do arduino
  6.  * GND -> GND do arduino
  7.  * Rx -> Pino 10 arduino
  8.  * Tx -> Pino 11 do arduino
  9.  *
  10.  * Antes de ligar o arduino e o modulo bluetooth segure pressionado no botão que existe no modulo bluetooth, e então ligue a alimentação. Segure ate que o modulo comece a piscar lentamente.
  11.  * Abra a Serial do arduino e digite:
  12.  * AT
  13.  * O modulo deve responder:
  14.  * OK
  15.  
  16.  * Agora digite:
  17.  * AT+NAME=novo-nome
  18.  *
  19.  * O modulo deve responder:
  20.  * OK
