Is it possible to have an Adafruit music maker shield and a sensor connected to the same Arduino? Are the analog I/O pins on the Arduino still available for sensors when there is an Adafruit Music Maker shield attached to it? I want to play a sound file, but only when a PIR sensor senses motion.
If you look at the PCB of the Adafruit Music Maker here:

You can see that there are no connections on the analog I/O of the Arduino.
