Hello, I'm a newbie and have a few questions.  I am interested in building a sonic installation in a public park.  I would like to use IR sensors to detect proximity of people to trigger a behavior of pre-recorded audio playback through speakers.

I have done an arduino sketch, but it was attached to my computer.  I would like to create the finished product wirelessly.

Are there any suggestions for what I am thinking?

Thank you!

Sure - hook arduino with bhagman's MP3 shield and your sensors, run the audio into an amplifier so it can be heard above traffic.

Hello, and thank you for the reply.
Since this would be in a place w/out power, I would need all of it to work wirelessly.
Sensor to microcontroller, to behaviour.
Yes?

So you really need 2 microcontrollers talking to each other.
The sensor tells micro1when proximity is met, micro1 sends a message to micro2 which is colocated with the sound creation/amp to play the sounds.
How far apart is the sensor and sound source?
