//  ECET 3710 - C# code

//

//  ProjectPartA Class {PartA.cs}

//  by Younes Ouzbier

//

//  Demonstrates basic GPIO input and output and the use of the WiringPi delay 

//  functionon the Raspberry Pi using a C# wrapper for the WiringPi library of 

//  hardware access routines.

//  

//  The programs basic function is to light all the LEDs when switch A is pressed, and

//  to cycle all the LEDs in a knight rider pattern where only one LED is lit at a time 

//  and the LED appears to bounce from side to side when only switch B is pressed.
