/diy/ - Do It Yourself

I'm feeling rather stupid. I'm trying to get a 3.3v logic controller (f.e. an esp8266 or another arduino-like) to output between 6-12 volts (to power some leds/small pumps etc) but can't seem to figure out how to do this. I've ordered some mosfets but I'm afraid I made a mispurchase as those seem to only trigger from 10v.

How could I get the 3.3v of an esp8266 (or the 5v of an raspberry/etc) up to 6 or 12 volts while allowing some (at least an Amp, preferably a lot more) current through?
