Imagine a 5v circuit which has a switch on it. When that switch is pressed, I want to close the circuit, when it isn't I want the circuit to be broken.
OK, what I am looking to do is replace the switch with some sort of component that can be controlled by a pic chip. I want to pass a voltage out of a pin from the pic and have the circuit connected. I dont want to pass a current to the circuit, just to connect it.
What (component) do I need to achieve this please?
