Blinking an LED with LilyPad Arduino

Step up from a plain sewn circuit to a sewable computer. The LilyPad Arduino is a washable microcontroller you program from your PC, then run on a coin cell — so your fabric can blink, fade and react on its own. This project sews an LED to the board and uploads the classic 'blink' sketch: the gateway to every sensor-driven wearable that follows.

Sew the LilyPad Arduino and an LED

Sew a LilyPad Arduino Simple board and a LilyPad LED onto felt with conductive thread: the LED's + tab to numbered pin 5, and the LED's - tab to the board's - tab. Loop 3–4 times through each hole, trim tails, and keep the two lines from crossing.

Connect the FTDI programmer

Plug a LilyPad FTDI Basic Breakout onto the board's 6-pin programming header (line up GND to GND, DTR to DTR) and connect it to your computer with a USB cable. Install the free Arduino IDE, then choose the LilyPad Arduino board and the FTDI's serial port under Tools.

Upload the blink sketch

Paste this sketch into the Arduino IDE and click Upload. It flashes the LED on pin 5 on and off twice a second.

lilypad_blink.inoarduino
// Blink an LED sewn to a LilyPad Arduino
// The LED's + tab is stitched to pin 5, its - tab to the board's - (GND).

const int LED_PIN = 5;   // LilyPad LED sewn to pin 5

void setup() {
  pinMode(LED_PIN, OUTPUT);   // pin 5 drives the LED
}

void loop() {
  digitalWrite(LED_PIN, HIGH); // LED on
  delay(500);                  // wait half a second
  digitalWrite(LED_PIN, LOW);  // LED off
  delay(500);                  // wait half a second
}

// TRY THIS:
// - delay(100) for fast blinking, delay(2000) for slow
// - different ON and OFF times: HIGH delay(800), LOW delay(200)

Go wireless on a coin cell

Unplug the FTDI. Sew a LilyPad coin-cell battery holder to the board — + tab to +, - tab to - — and drop in a CR2032. Switch it on and the LED blinks on its own, no computer attached. Your fabric now runs its own program.

Experiment

Re-attach the FTDI and change the sketch: adjust the delays for a heartbeat rhythm, or sew a second LED to another pin and blink them in turn. This is the base every LilyPad sensor project builds on.
