What you need

• Maple Mini R3 Board
• Arduino IDE
• USB cable
• Example circuit (check the datasheet)

Steps

1. 1. Install Arduino IDE (check the official website).
2. 2. Connect the board with the USB cable.
3. 3. Select ‘Arduino SAMD Boards’ > ‘LeaF Labs Maple Mini R3’ in the ‘Tools’ menu.
4. 4. Load the example sketch ‘Blink’ (File > Examples > 01.Basics > Blink).
5. 5. Wait for the default LED to turn on and off.
6. 6. Check for the presence of a bootloader (check the datasheet).
7. 7. Connect an example circuit (check the datasheet).
8. 8. Load a custom sketch.

Example code

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

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);
  delay(1000);
  digitalWrite(LED_BUILTIN, LOW);
  delay(1000);
}
```

Mini project

Build a simple LED counter using the board and output pins.

Common mistakes
