Making a Color-Changing LilyPad Patch
Sew a patch that glows in any color. A single RGB LED holds red, green and blue elements; by fading each one with the microcontroller's PWM pins you mix millions of colors and cycle through the rainbow. The e-textile version of the classic RGB colour-mixing project.

Sew the board and RGB LED
Sew a LilyPad Arduino onto felt. The RGB LED has four legs — bend each into a small loop so it can be sewn. Wire the common cathode (the longest leg) to -, and the red, green and blue legs to pins 5, 6 and 9. Keep the four lines from touching each other.

Paste this sketch and upload. It fades the LED through red, green, blue and the mixes using analogWrite (PWM).

The LED fades through the colors on its own. Make your own by changing the three numbers in setColor(red, green, blue) — each 0–255. Note: at the LilyPad's lower voltage blue and green look a little dimmer than red, which is normal for RGB LEDs.

Plug a 3.7 V LiPo into the LilyPad Arduino's JST connector and switch on — the higher voltage also makes the colors brighter. Sew the felt onto a bag or costume for a colour-changing glow.
