i have a 12v dc 2.5A solenoid, and am looking to control it using a bs2 homework board. i assume i need a 12v 2.5A power supply to run this, but as far as control goes, do i need a relay, a transistor, both? please help.

    I'd use a suitable MOSFET. Don't forget to put a diode across the solenoid.
