안녕하세요 코드에 관련해서 질문드리고 싶습니다. 도저희 머가 문제인지 모르겠어서.. 소개를 하자면 빗물을 감지하면 모터 회전수를 정해 그만큼 회전시켜 창문을 닫는 시스템인데요 아두이노로만 할때는 정확하게 다 구동이 되는데 와이파이 쉴드로 와이파이로 블링크라는 어플을 사용하여 원격으로도 창문을 개폐할수 있는 시스템을 추가할려합니다 그런데 코드를 다 합치면 모터가 역회전하거나 잘 돌아가지도 않고 와이파이도 접속이 안됩니다 다른예제를 하면 와이파이도 잡히고 잘되는데 뭐가 문제일까요?? 코드 확인하고 수정할부분이 있는지 오류가 왜 나는지 알려주세요ㅠ 부탁드려요ㅠㅠ 아두이노 우노, 와이파이는 esp8266 입니다
/************************************************************ ESP8266_Shield_Demo.h SparkFun ESP8266 AT library - Demo Jim Lindblom @ SparkFun Electronics Original Creation Date: July 16, 2015 https://github.com/sparkfun/SparkFun_ESP8266_AT_Arduino_Library
This example demonstrates the basics of the SparkFun ESP8266 AT library. It'll show you how to connect to a WiFi network, get an IP address, connect over TCP to a server (as a client), and set up a TCP server of our own.
