Hi,
Im completely green, have only been watching around 100 videos and are now starting to experiment myself.
Im starting out with making a startling scarecrow to scare away the deers from my rose garden.
So I thought I would make it with a PIR which sends voltage to a transistor which activates a mosfet for a larger current to run a motor or a solenoid of some kind.
The following circuits PIR does work (blue LED lights). It lights up the LED for 3 sekunds and turns off.
The circuits MOSFET also works fine (green LED lights) if I activate it manually with the wire floating in the air.
My question is, and I have tried several places, where do I connect the wire to activate the mosfet, and do I have a circuit that actually can do that?
The first photo should give you some information about the circuit.
It is suppose to run on 6-12 volts, I will adjust it when I figure out what its going to run.
