I use an Arduino ONE that has an output of 3.3V. I think the Arduino Pro Mini (5V version) also has an output of 3.3V that can be used instead of pin 12. If you do not have that output you will have to use a LM117 to pass the 5V to 3.3V, as illustrated in the diagrams. Hi Vallekano , Thanks for you...
