A system for improving a basketball player's ability to shoot basketballs towards a basketball hoop having an improved ball sensor is disclosed. An interface allows a player to select various locations for a ball ejector to launch basketballs to. A hollow protrusion extends though the net of the basketball hoop and has a microphone positioned therein. A processor compares audio signals generated by said microphone to pre-recorded sample audio signals of a basketball passing through the net of the basketball hoop to determine if a basketball shot was successfully made.
