// Basics Demo
  // First... On
//   digitalWrite(led1, HIGH);   // Turn ON the LED pins
//   delay(1000);               // Wait for 1000mS = 1 second

//   // Now... Off
//   digitalWrite(led1, LOW);   // Turn OFF the LED pins
//   delay(1000);               // Wait for 1000mS = 1 second
  // rinse + repeat

  // The core of your code will likely live here.

  // Example: Publish event to cloud every 10 seconds. Uncomment the next 3 lines to try it!
  // Log.info("Sending Hello World to the cloud!");
  // Particle.publish("Hello world!");
  // delay( 10 * 1000 ); // milliseconds and blocking - see docs for more info!
  
  
  
// Exercise 1

//   delay(3000);               // Wait for 3000mS = 3 second
