Connecting The Lilypad Arduino And Arduino Ng; Sewing The Lilypad Arduino - Sparkfun Electronics LilyPad Arduino Manual

Connecting the LilyPad Arduino and Arduino NG

You can also use an Arduino NG to connect the LilyPad Arduino to your
computer, using the Arduino NG as a power supply and USB/Serial connection.
Just remove the ATmega8 or ATmega168 from the NG and then use jumper
wires and alligator clips to attach the TX, RX, +, and - tabs on the LilyPad to the
corresponding pins on the NG. Here's a photo.

Sewing the LilyPad Arduino

The hole on each tab of the LilyPad is large enough for a sewing needle to pass
through. You can make both electrical and physical connections with stitching in
conductive thread. Sew through the holes several times to insure good contact.
Here's a picture showing a sewn LilyPad:
