Led_buttons.ino

/*Program Name: Buttons
  This program turns on the led lights with the use of buttons.
  Button 1 will turn on led 1 while button 2 will turn on led 2.
  If button 1 is pressed and led 1 is turned on, led 2 should be turned off
  and vice versa. The lights should alternate in turning on and off as the buttons
  are pressed.

   SETUP:
   Things you need:
   1) 2 LED pins
   2) 2 buttons
   3) 2 10kΩ resistors
   4) 2 560Ω resistors
   5) 12 wires
   6) Arduino UNO and Breadboard
   7) USB Wire
