Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

위와 같이 노드 설정에서 MAC 주소값을 넣어 주시면 됩니다.

MAC 주소값을 얻는 방법은 다음과 같습니다.
1. 아두이노 시리얼 모니터 확인
2. 4채널 보드의 ESP32 칩 겉면 확인

1) 아두이노 시리얼 모니터 확인

2_mac check

위와 같이 시리얼 모니터에서 Mac address를 확인할 수 있습니다.

2) 4채널 보드의 ESP32 칩 겉면 확인

3_esp32 mac

Mac address만 정상적으로 기입 하시면 자동으로 MQTT 서버에 접속 됩니다.


구동 방식 ( 입력 데이터 구분 )

해당 노드는 2가지의 기능을 갖고 있습니다.

1. 릴레이 개별 구동
2. 릴레이 전체 구동

1) 릴레이 개별 구동

image

입력되는 데이터의 형식 입니다. 두 가지 key 중
outNo는 릴레이 순서(0 ~ 3) value는 on/off 입니다.

2) 릴레이 전체 구동

image

개별 데이터와 다르게 한 msg로 제어하고 싶을 때는 위와 같이 No0 ~ No3 으로 입력 해주세요.
