• Power – The LilyPad Arduino can be powered via the USB connection or with an external power supply. If an external power supply is used, it should provide between 2.7 and 5.5 volts. This can come either from an AC-to-DC adapter (wall-wart) or battery. Again, don’t power the LilyPad Arduino with more than 5.5 volts, or plug the power in backwards: you’ll kill it.

• Programming – The LilyPad Arduino can be programmed with the Arduino Arduino Software (IDE). Select “LilyPad Arduino” from the Tools > Board menu (according to the microcontroller on your board). For details, see the reference and tutorials. The ATmega168V or ATmega328V on the LilyPad Arduino comes preburned with bootloader that allows you to upload new code to it without the use of an external hardware programmer. You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header. While the holes are too small to insert pins into, you can insert male header pins into the ISP connector on your programmer and press them against the ICSP header on the board (from above). See these instructions for more information.

• Physical Characteristics – The LilyPad Arduino can be powered via the USB connection or with an external power supply. If an external power supply is used, it should provide between 2.7 and 5.5 volts. This can come either from an AC-to-DC adapter (wall-wart) or battery. Again, don’t power the LilyPad Arduino with more than 5.5 volts, or plug the power in backwards: you’ll kill it.

• Washability – Wash at your own risk – we do ;). We recommend washing projects by hand with a mild detergent. Drip dry. Make sure you remove your power supply first!
