Making a LilyPad Night-Light
Give your fabric a sense of sight. A LilyPad light sensor tells the microcontroller how bright the room is, and a short program switches an LED on when it gets dark. Sew it into a bag, a hat or a bedside patch for a soft glow that only appears at night — your first sensor-driven wearable.

Sew the board, sensor and LED
Sew a LilyPad Arduino, a LilyPad light sensor and a LilyPad LED onto felt. Wire it: the LED's + tab to pin 5 and its - tab to -; the sensor's + tab to the board's +, its - tab to -, and its signal (S) tab to analog pin A2. Keep the power (+), ground (-) and signal lines from crossing anywhere.

Upload the night-light sketch
Paste this sketch and click Upload. It reads the light sensor and turns the LED on whenever the room is darker than the threshold.
Calibrate the threshold
Calibrate the threshold
Cover the sensor with your hand — the LED should come on; in a bright room it should stay off. If it triggers too early or too late, change the threshold number in the sketch and re-upload: higher turns it on in more light, lower waits for darker.
Go wireless and wear it
Go wireless and wear it
Unplug the FTDI, sew a LilyPad coin-cell holder to the board (+ to +, - to -), drop in a CR2032 and switch on. Sew the felt onto a bag, hat or cushion — it now glows on its own whenever the light drops.
