is there a relay that if feeded 5V it will be turned on and 220V will be the voltage to run through the relay? if there is what can you suggest?

i'm asking this because i'm making a device that will connect to the parallel port (aka printer port) of a computer that will controll a bell (bells that are used in schools). the relay is the only one left that i have no idea what to put.

please help me, its just a school project for me. i'm just new to building this kind of stuff.

thanx....
