<div><br></div><div><div>There's a lot out there. A solenoid is simple but most of the ones I see for sale need you to add a spring yourself and mount them somehow. An RC servo could work. Would a spinning motor with an arm and something at the end be close enough to a "tap"? If you can get away with something that isn't perfectly straight then there are going to be easier options IMHO.</div>
