Snake Pit

I often work on display and interaction projects for our local Aquarium. This one is a simulated snake sound as a reaction to someone putting their hand in a hole in a snake put that is fabricated in the wall of an exhibit.

The project is made from:

• An arduino uno
• A 3 watt stereo amplifier
• http://www.amazon.com/gp/product/B008NZ7110/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1
• A Waveshield 
• http://www.adafruit.com/products/94
• An optical sensor
• http://www.adafruit.com/products/164
• 2 speakers
• 9v power supply
• http://www.amazon.com/gp/product/B004LX146Q/ref=oh_details_o08_s00_i00?ie=UTF8&psc=1

I used the tutorials provided for the wave shield as the base code for the project and added code to convert the sensor analog value to a threshold function that will play the snake sound when the sensor is interrupted inside a preset distance.
