Controlling switches with a PIC

[TonyA]

Thank you.

Is it possible to just use a 2N2222 transistor?

I found this schematic, however my application is a little different. (It got me thinking though):

If the relay was omitted from that circuit, and since I just need to switch an incoming wire to ground via the transistor. The "switching" would be controlled by the PIC.

Would I just connect B of the transistor to the pic pin, C to the incoming wire and E to ground?

Then toggle the PIC pin attached to B of transistor? Would this send my "incoming wire" to ground?

Thanks for the help.
