# [RE]이더넷 쉴드와 아두이노를 이용해 IoT 스마트 콘센트를 만들다

## Article

This UXC is about creating a simple externally controllable IOT outlet using an Arduino Mega, an Ethernet shield, and a relay module.

Remove the sheath of the multi-tab wire and connect the 220V line to relay off and on (see circuit below)

Later, the relay module is connected to the mega so that it can be controlled by the Arduino mega.

The code used the web server code.

The author said he was able to check the messages toggled to cereal during the test,

It is said that the relay is actually operating and the power is ON-OFF.

본 UXC는 아두이노 메가와 이더넷 쉴드, 릴레이 모듈을 사용하여 간단하게 외부에서 제어 가능한 IOT 콘센트를 제작한 컨텐츠입니다.

멀티탭의 전선의 피복을 벗겨내 220V 라인을 릴레이로 끄고 켤 수 있게 연결(아래 회로 참)

![](https://maker.wiznet.io/upload/ckeditor5/279227998%5F1698961351%2Epng)

이후에 아두이노 메가에서 제어 가능하게 릴레이 모듈을 메가에 연결.

코드는 웹서버 코드를 사용하였습니다.

저자가 Test시 시리얼로 토글되는 메시지를 확인할 수 있었다고 하였고,

![](https://maker.wiznet.io/upload/ckeditor5/279227998%5F1698961453%2Epng)

실제로 릴레이가 동작하여 전원이 ON-OFF 됨을 확인하였다고 합니다.
