i need make speaker turn on play music when sensor active waving off walking next , turn off when walked next

you need form of sensor detect presence of (moving) object. possible options pir sensor or hc-sr04 (there might others).

what kind of music? can compose , store simple melody in memory , play that. there mp3 shields can play songs. think come sd card reader; can little search 'arduino mp3'.
