Hello Tux Leonard, thank you by your answer. Using +5v I had success too, but I would like to usage only +3v and convert it to +5v like this circuit
http://electronics.stackexchange.com/questions/56093/how-to-use-a-3v-output-to-control-a-5v-relay But I 'm having difficult understand this and simulate with BBB or RPi If possibe, could you help me pls? Thank you o much and happy new year for everyone!!!!
