Create C,C++ Project on Raspberry Pin. Control LED

Step 1: Install Git core
Git is code repository system, where you can store and make version of code online. To use GIT
you have to install Git core in your raspberry pi.

Command To install GIT Core.

sudo apt-get install git-core

Step 2: Download code from git branch,

Once the GIT core is installed, you have to install it download the wiringPI library from git branch.

Command to download wiringPI library:
git clone git://git.drogon.net/wiringPi

Step 3: Build and install wiring pi library

Once downloaded, go to directory
cd wiringPi

Then run below command.
./build

Step 4: Write your code. 

Open your text editor, Nano in my case, copy following code to your editor.

#include <stdio.h>
#include <wiringPi.h>

int main (void)
{
  printf ("Raspberry Pi blink\n") ;
  if (wiringPiSetup () == -1)
    return 1 ;
  pinMode (0, OUTPUT) ;         // 

  for (;;)
  {
    digitalWrite (0, 1) ;       // On
    delay (500) ;               // mS
    digitalWrite (0, 0) ;       // Off
    delay (500) ;
  }
  return 0 ;

}

Step 4: Save , Exit, Compile and Run

Command to compile

1	gcc -o blink blink.c -lwiringPi

after successful compilation run the executable.

1	sudo ./blink
