loop()¶

After creating a setup() function, which initializes your sketch, the loop() function gets called repeatedly, allowing your program to change and respond. Use it to actively control your Maple board.

Example¶

int buttonPin = 38;

// setup initializes serial and the button pin
void setup() {
  SerialUSB.begin();
  pinMode(buttonPin, INPUT);
}

// loop() checks the button pin each time it executes,
// and will print 'H' if it is pressed, 'L' otherwise
void loop() {
  if (digitalRead(buttonPin) == HIGH) {
    SerialUSB.println('H');
  } else {
    SerialUSB.println('L');
  }

  delay(1000);
}
