Beat with Buzzer - Arduino Sketch

beat_buzzer_ard_sketch

/*

  Copied my first sketch from the blink sketch and modified it 11Jan2015- Fernando 
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the Uno and
  Leonardo, it is attached to digital pin 13. If you're unsure what
  pin the on-board LED is connected to on your Arduino model, check
  the documentation at http://arduino.cc

  This example code is in the public domain.

  If you attached a LED and a Buzzer in the circuit it plays a beat
  
  I added a 220Ohm resistor and buzzer in paralle with the 220ohm resitos and LED
