	* Finally, copy and paste the interrupt routine (all of the code at the bottom of the wiki) to the bottom of your code (outside the main function).		* Finally, copy and paste the interrupt routine (all of the code at the bottom of the wiki) to the bottom of your code (outside the main function).
	This creates an interrupt routine (to be discussed in class) that will stop your code when a key is pressed on your keyboard. It will check to see if this key is a ‘c’. If it is, LED2 will turn on and LED3 will turn off. If the key is not a ‘c’, LED2 will be off and LED3 will turn on. No matter what key is pressed, LED1 will toggle on and off.
