baseball pitching machine auto feeder how to?

I made a very simple pitching machine...actually a soft toss machine. It is a pvc pipe assembly that when set up, dad simply "loads" a ball in the downward angled pipe and it "drops" in front of the batter. My question is: the downward angled pipe can be long enough to hold a dozen balls - what can I use to create a mechanism that allows one ball to drop every 5 seconds automatically?
