I am looking to make a scarecrow based off of this this year and have a few additions I need guidance with. Essentially I am hooking up a fog machine and a loop track of demonic laughter so that he sprays fog and laughs. Now based off of several tutorials I can easily use a PIR sensor and plug a speaker and motor in to run when it goes off but the fog machine needs to be on but have its "button pressed" when the sensor goes off. I have a general idea of what I want to do but need to know how I can trigger a button that is connected to my machine. I dont mind taking the button apart and rewiring it just not sure how. Can anyone point me in the right direction?
