 // V1 LED Widget is blinking

 *
 * App project setup:
 *   LED widget on V1
 *   LED widget on V2
 *   LED widget on V3
 *
 * WARNING :
 * For this example you'll need SimpleTimer library:

{
  if (led1.getValue()) {
    led1.off();
    BLYNK_LOG("LED on V1: off");
  } else {
    led1.on();
    BLYNK_LOG("LED on V1: on");
  }
}
