[8] 아두이노를 활용한 부저 알람

데이터 학습을 통해 싸우는 장면을 동영상, 웹캠을 통해 확인할 수가 있었습니다.
하지만 확인만 될뿐 알려주는 기능은 없었기에 어떻게 활용을 해야하나 생각을 많이 하였습니다.
결과로는 아두이노를 통한 부저 알림과 GPS위치 확인등이 있었습니다.
아두이노 다운로드 과정은 쉽게 찾아 보실 수 있습니다.
운영체제에 맞게 다운받으시면 됩니다. (특별한 환경설정은 없고 사용하시는 기기에 맞게 설정하셔 사용하시면 됩니다.)
설치가 완료된 후 좌표값과 서버와 통신을 설정하였기 때문에
Bounding Box의 좌표를 서버로 보낸것을 다시 불러와야 했기에 Arduino - Ethernet - WebClient예제를 활용하였습니다.

아두이노 우노 Ethernet IP주소는 Arduino - Ethernet - DhcpAddressPrinter예제를 활용하였습니다.
아두이노 우노의 MAC주소 같은경우 정품은 뒷면에 적혀있다고 들었는데 저는 적혀 있지 않았습니다.
