All Done.
NOTE: To compile programs with wiringPi, you need to add:
-lwiringPi
to your compile line(s) To use the Gertboard, MaxDetect, etc.
code (the devLib), you need to also add:
-lwiringPiDev
to your compile line(s).

5. gpio 사용법
- gpio -g mode 핀번호 input( 혹은 output)
- gpio -g write 핀번호 1( 혹은 0)
- gpio -g mode 핀번호 up ( 혹은 down, tri )
- 핀번호는 BCM 기준이다
6. ~/wiringPi 디렉토리 구조
7. gpio readall
8. gpio output test
BCM 17번 핀을 Output 모드로 변경
9. gpio output test
BCM 17번 핀 값을 High로 변경
10. ~/wiringPi/example 디렉토리 구조
