Tutorial: How to use LilyPad Arduino USB – ATmega32U4 board

The LilyPad Arduino USB board is ideal for touch and wearable electronics projects. It is perfect for beginners who want to start creating interactive devices.

What you need

• LilyPad Arduino USB
• USB A-micro B cable
• Arduino IDE software

Steps

1. Step 1: Download and install the Arduino IDE from the official Arduino website.
2. Step 2: Connect the LilyPad USB board to the computer via the micro-B USB cable.
3. Step 3: Open the Arduino IDE, select ‘Boards > Arduino Lilypad USB’ from the list of available boards.
4. Step 4: Verify that the board is recognized by the computer’s operating system (you should see a new connected device).
5. Step 5: Upload the example sketch ‘File > Examples > 01.Basics > Blink’ to the board.
6. Step 6: Check that the integrated LED is blinking according to the uploaded code.
7. Step 7: Try modifying the sketch to change the on and off intervals of the LED.
8. Step 8: Explore other examples in the ‘File > Examples’ menu to discover additional features.

Example code

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // accendi la LED interna
  delay(1000);                       // attesa di un secondo
  digitalWrite(LED_BUILTIN, LOW);    // spegni la LED interna
  delay(1000);                        // attesa di un secondo
}

Mini project

Create an interactive belt that changes color based on body temperature. Use temperature sensors and RGB LEDs.

Common mistakes
