I have a question about My ROV control system.
I am building an ROV and I need to know whether this control board will work. I planed on Running 1 Cat5 and 1 set of speaker wires to control and run systems on-board. When I flip a switch on the control panel, a 3v signal is sent down the Cat5 wire to the base of a transistor, which opens the flow of power between the Emitter and collector.
My main question is, does a transistor work as a switch? Example. A signal enters the Base and opens the other two connections. Is this right?
Oh, and the other two pictures are what i plan for it to look like. I am building it using the motors from one project (posted recently) , the frame another, and my own control. I will post an instructable as soon as it is done.
