Blinky lights, in all shapes and sizes, are always a good thing to have. These micro LilyPad LEDs cover the tiny end of the size spectrum, and come in white, red, yellow, blue and green.
This is the LilyPad Arduino Simple Board. It's controlled by an ATmega328 with the Arduino bootloader. It has fewer pins than the LilyPad Arduino Main Board, a built in power supply socket, and an on/off switch.
The LilyPad Simple Power is a board that lets you connect a battery (or other power source with a 2-pin JST connector) and switch it on or off, that's it!
Magnets. How do they work? We're going to guess magic. This particular set of magnets are pretty darn strong, are able to rotate freely, and conduct electricity. That's a pretty darn good kind of magic, if you ask me.
The LilyPad Battery Connect simply gives you a connection point for a battery or anything else you might want to plug in to your LilyPad system. It consists of a single 2-pin JST connector on a small LilyPad board with positive and negative terminals.
These boards allow you to use your own 5mm LED as a LilyPad LED.
