ok thanks for the tip i will look into it :thumbsup
special note:
** If you -do- in fact get an Arduino Pro-Mini..
it does -not- have a USB socket on it.. you need to buy a USB > Serial adapter... (around $1.00-2.00 USD)
Or you can buy an Arduino Nano (but is a little bigger than the Pro-Mini.. and for this project... it looks like size DOES count!)
That being said..
you dont even need an Arduino/microcontroller..
you can get a switch, some coin cell batteries... and some resistors/leds..
