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.
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);
}
