so i followed this LED strip tutorial: Digital RGB LED Strip tutorial basically I've followed the circuit with the TIP 122 transistor, and I'm trying to fade between 3 led strips. they all work, except one of the strips will not completely turn off. I'm not sure if anyone has some quick suggestions…

LED won't shut off completely.

The link you posted doesn't mention a TIP122 transistor. Maybe you posted the wrong link?
