Hello
I'm fairly new to small electronics. I know the basics of ohms law and some other little things here and there about circuit basics. So I have drawn up this basic circuit and tried to provide all the info necessary to help me select the right mosfet for my application. My attempts at picking the right one have been frustrating at best as all the specs are a little confusing to me. Basically if the PIR senses movement, it'll send a signal to the Arduino, which then sends power to the mosfet to take power from a separate battery and finally activate the motor but only for a short moment and it should be fairly infrequent.
So what I've figured out so far is I need a logic gate mosfet, n-ch. Almost all will handle the 6V battery I've attached to it. But the other mosfet specs I get confused on. So if someone has a mosfet suggestion for my application I'd greatly appreciate it! ...and here is the circuit:
