Indeed there is many project like available on internet.
This one use a tilt switch as trigger
1 x Arduino board (http://shop.snootlab.com/lang-en/arduino/68-arduino-duemilanove.html)
7 x 500 ohms resitors ¼ W
7 x basic red leds
1 x 10 k ohms resitors ¼ W
1 x tilt switch (I use this one http://shop.snootlab.com/lang-en/parts/96-tilt-sensor.html)
A piece of prototyping board plated holes
Male header (0,1") 1 row, 40 pins (need only 28 for complet arduino connexion , and realy need 10 for this project) http://fr.mouser.com/ProductDetail/FCI/68004-236/?qs=sGAEpiMZZMtsLRyDR9nM10aphOtlQBeldG%252bobNTQj6E%3d
Tools
A PC to program the arduino
An soldering iron
Some tin
A cutter

If you put a motor, you have to use a REED switch (http://uk.mouser.com/ProductDetail/MEDER-electronic/KSK-1C90U-2034/?qs=Gn6sDDtUhEnntk6ouTT%252bgA%3d%3d), a hall effect sensor (http://www.sparkfun.com/products/9312) and magnet. You can also use a led + photo transistor .
A last point, if you use a motor with really high speed, the code can fail because it doesn’t use interruptions...
Please post a link with the result of your experimentation

I'm thinking of not using a switch at all.. you just plug the power to the arduino and it works
And sorry I don't know what do you mean with interruptions ( I'm new to arduino)
It's for synchro. It you don't use a sensor it will work like this

or this http://youtu.be/9l2Vnq2NwHg
But if you use a sensor,

In this last case the sensor is an opto isolator.
Last point, interruptions is the french word for Interrupts (sorry for my bad english)==> http://arduino.cc/playground/Code/Interrupts
