Hi everyone! One one of the useful things, especially if you have many boards that you regularly experiment with is to have some cheat sheets, ideally attached or close to your regular board. The reason is that in many cases one forgets the driving voltages an so on and might make toast out of an expensive board. I have these two texts on stickers behind the plastic boards I have made to hold my Arduinos:

Arduino Diecimilla
The power source is selected by the jumper between the USB and power plugs. To power the board from the USB port (good
for controlling low power devices like LEDs), place the jumper on the two pins closest to the USB plug. To power the board
from an external power supply (6-12V), place the jumper on the two pins closest to the power plug. Either way, connect the
board to a USB port on your computer. The power LED should go on. *

Arduino Lilipad
The LilyPad Arduino is more fragile and easy to break than a regular Arduino board. Don't connect more than 5.5 volts to
the + tab or reverse the power and ground pins of your power supply, or you will very likely kill the ATmega168V on the
LilyPad Arduino. You can't remove the ATmega168V, so if you kill it, you need a new LilyPad. *

As you progress in your development these cheat sheets will grow, and will serve as handy reminders of data you need to have at hand.
