I am using a Arduino DUE for my project.
The DUE does operate with 3,3 V instead of 5 V like the other Arduino derivates.
Apparently I have a few external devices, which require 5 V to trigger them, like a relay, stepping engine driver and so on.
I could use several transistors, to convert the 3,3 V to 5 V... Never the less this is something I try to avoid.
I would like to know if there is a device to do the logical conversation between 3,3V and 5V like a 1 to 1 gatter IC or something, which is recommanded for those task.
