I have 4 basic independent circuits, each circuit consists of 1 x AA battery, some wire, a micro switch and a light bulb.
I would like to control them from a single switch. So that upon the first switch depression, only circuit 1 will illuminate; switching off when the button is released. The second press of button illuminates circuit to release and so on.
I have managed to achieve the desired result with my raspberry pi a micro switch and some relays.
Is there an off the shelf, stand-alone solution that could replace raspberry pie?
My experience with electronics is purely through experimentation, which has made researching this difficult, I don't know where to start. I am not looking for a step by step just a few keywords to point me in the right direction and I'll work it out myself from there.
