아두이노 개발 연습 - wido arduino web server + radiation kit

wido arduino web server + radiation kit을 부착한 코드이다.

웹서버와 방사선측정 킷과의 연동을 하고 있으며

방사선 킷 구입처는 아래와 같다.

http://www.rhelectronics.net/store/radiation-detector-geiger-counter-diy-kit-second-edition.html

ems express 비행기 배송으로 약 18만원정도 들었다.

radiation kit으로서 아두이노와 연동도 가능한 유일한 kit제품이다.

아래 작성한 코드에는 특별히 interrupt함수가 들어가 있어서 방사선 측정 량을 계산해준다.

웹서버는 서버로서 text/plain으로 값을 전달해준다.

This example does a full test of core connectivity:

* Initialization

* SSID Scan

* AP connection

* DHCP printout

* DNS lookup

* Ping

* Disconnect

It's a good idea to run this sketch when first setting up the

module.
