led <- hardware.pin9; // LED Pin
ledState <- 0;        // Current state of the LED

// Configure the LED
led.configure(DIGITAL_OUT, ledState);

function blink() {
  // run blink() again in half a second
  imp.wakeup(0.5, blink);
  
  // Flip the state, and write it to the pin
  ledState = 1 - ledState;
  led.write(ledState);
}

// Call blink() to start the loop
blink();
