led.blink()

Makes the red LED blink.

led.blink toggles the LED on and off at a rapid or slow pace depending on the interval given. The interval is the time (in milliseconds) between blinks, meaning the bigger the number the slower the pace of the blinks.

Examples

onBoardEvent(buttonL, "press", function(event) {
  led.blink(200);
});

Blink Buttons

var blinkRate = 50;

onBoardEvent(buttonL, "down", function(event) {
  blinkRate = blinkRate - 10;
  led.blink(blinkRate);
});

onBoardEvent(buttonR, "down", function(event) {
  blinkRate = blinkRate + 10;
  led.blink(blinkRate);
});

Stop the Madness!

If the led is blinking too slowly or too fast, stop the led altogether.

//If the led is blinking too slowly or too fast, stop the led altogether.
var blinkRate = 50;

onBoardEvent(buttonL, "down", function(event) {
  blinkRate = blinkRate - 10;
  led.blink(blinkRate);
  if(blinkRate < 10){
  	led.off();
  }
});

onBoardEvent(buttonR, "down", function(event) {
  blinkRate = blinkRate + 10;
  led.blink(blinkRate);
  if(blinkRate > 200){
    led.off();
  }
});

Syntax

led.blink(interval);
