Without making me feel like a total idiot can someone please explain to me what the function of these transistors are?
I'm working on a PIR circuit with a counter. I want to tie the output of the PIR to the input of the counter, the connection diagrams on both the datasheets call for a transistor on each (or when used together just one transistor I imagine?) but I need help understanding what the transistor is doing?
PS, I never could thoroughly wrap my brain around transistor theory in tech school.
