Hello, I hope I have put this in the write topic, if not, can you please help me do so. Do the output pins on an Arduino Mega 2560 (eg. pins 1,2,3,4,5,6,7,8,9,10,11,12,13,...) have an output of 5v? Thank you in advance.

You can't run a mini humidifier directly from an output pin. You need some kind of controller or power amplifier. It could be a module or a custom circuit.
