====Objectives====
to repeat the functioning LED program but write a c program to accomplish this

====Prerequisites====
 raspberry pie,monitor, keyboard, data cable, hdmi to usb cable, network cable

====Background====
The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools.[7][8][9][10][11]

The Raspberry Pi is manufactured through licensed manufacturing deals with Newark element14 (Premier Farnell), RS Components and Egoman. All of these companies sell the Raspberry Pi online.[12] Egoman produces a version for distribution solely in China and Taiwan, which can be distinguished from other Pis by their red coloring and lack of FCC/CE marks. The hardware is the same across all manufacturers.

====Code====
<code>

#include "rpi.h"

int main()
{
  if(map_peripheral(&gpio) == -1) 
  {
    printf("Failed to map the physical GPIO registers into the virtual memory space.\n");
    return -1;
  }

  // Define pin 7 as output
  INP_GPIO(7);
  OUT_GPIO(7);

  while(1)
  {
    // Toggle pin 7 (blink a led!)
    GPIO_SET = 1 << 7;
    sleep(1);

    GPIO_CLR = 1 << 7;
    sleep(1);
  }

  return 0; 
}
</code>

====Reflection====

I am enjoying using the raspberry pi and seeing the possibilities that can be done wiith it
