-The provided program performs a similar operation as in the previous led1 project; it is your task to:+The provided source code (via grabit) is set up to provide the infrastructure to support both the LEDs and the buttons for this project. While you have to determine where they interface, the code will initialize the pins as appropriate. Your main task is to:
  
-  * expand the program to support FOUR LEDs+  * implement a program that counts 4 LEDs in the direction input specifies 
 +    * if one button is pressed, increment the count from the current value to 15, rolling over to 0 as needed 
 +    * if the other button is pressed, decrement the count from the current value to 0, rolling over to 15 as needed 
 +    * have a 50mS - 500mS delay between state changes 
 +    * pressing the button enables the change for that next state (after the current delay expires) 
 +  * implement support for FOUR LEDs
     * each LED connected to a unique GPIO line     * each LED connected to a unique GPIO line
-  * adapt the program to "act" on button presses. That is, it only proceeds from one step to the next when you press the button. +  * implement support for TWO buttons 
-    * NOTE: you may discover there to be "noise" or undesired behaviour when pressing the button and expecting a clean action. This can be cleaned up with additional program logic. +    * adapt the program to "act" on button presses. That is, it only proceeds from one step to the next when you press a button. 
-  * do NOT remove the delay. You may shorten (no shorter than 50mS) or lengthen the delay, but do not remove it entirely.+
