I am fairly new to Arduino. I am part of a group that teaches middle school aged girls about technology and the suggested Arduino workshop to have a light-up display. The idea would be to tap a canvas and have an led light strip flash with every tap.
I am in need of suggestions for materials and code to get started.
Thank you for your help.

Re: Arduino Controlled LED strip using knock sensor
If the tapping is on a canvas, an accelerometer would probably be the best sensor to use. An analog sensor like the ADXL335 is pretty simple to interface to an Arduino.

The Neopixel strips are also pretty easy to work with: http://www.adafruit.com/index.php?main_ ... ixel+strip
And you'll need a power supply for the leds. One of these will easily power a meter of the 30-led/meter strip: http://www.adafruit.com/products/276
There are tutorials and example code linked from the product description pages to get you started. And we're always here on the forums when you have more questions.
