IT 수업 24주차 (194) 아두이노 웹 연결 2

 

밑의 사진처럼 아두이노 키트를 만들어준다.

 

아두이노 IDE에 코드를 작성해서 업로드, 스케치 버튼을 눌러 실행시켜준다.

//LED
const int ledPin = 10;
char inputVal = 0;
//온도
float temp;
//조도
const int lightPin = A1;
//초음파
const int trig_pin = 11;
const int echo_pin = 12;
void setup() {
  Serial.begin(9600);
  pinMode(ledPin,OUTPUT);
  //초음파
  pinMode(trig_pin , OUTPUT);
  pinMode(echo_pin,INPUT);
}

void loop() {
  if(Serial.available()){
   	inputVal = Serial.read();
    if(inputVal == '1'){
      digitalWrite(ledPin,HIGH);
      Serial.print("LED:");
      Serial.print("ON");
      Serial.print("_");
     }
    else if(inputVal == '0'){
      digitalWrite(ledPin,LOW);
      Serial.print("LED:");
      Serial.print("OFF");
      Serial.print("_");
      
    }
  }
  //온도
  int val = analogRead(A0);
  temp = val*0.48828125;
  Serial.print("TMP:");
  Serial.print(temp);
  Serial.print("_");
  
  //조도
  int lightValue = analogRead(lightPin);
  Serial.print("LIGHT:");
  Serial.print(lightValue);
  Serial.print("_");
  
  //초음파
  digitalWrite(trig_pin,LOW);
  delayMicroseconds(2);
  digitalWrite(trig_pin,HIGH);
  delayMicroseconds(10);
  digitalWrite(trig_pin,LOW);

  long duration = pulseIn(echo_pin,HIGH);
  long distance = (duration/2)/29.1;

  Serial.print("DIS:");
  Serial.println(distance);


  delay(500);


}

 

그러면 현재 온도, 초음파, 조도 값이 출력되는 것을 확인 할 수 있다.

 

 

 

이번에는 인텔리제이로 와서 controller 패키지를 만들고 ArduinoController를 작성해준다.

package com.example.demo.controller;


import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@Slf4j
@RequestMapping("/arduino")
public class ArduinoController {

    @GetMapping("/index")
    public void index(){
        log.info("GET/arduino/index");
    }
}

 

그리고 restcontroller 패키지를 만들고 ArduinoRestController 클래스도 만들어 준다.

package com.example.demo.restconstroller;


import com.fazecast.jSerialComm.SerialPort;
import lombok.extern.slf4j.Slf4j;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;

import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import java.io.*;

@RestController
@Slf4j
@RequestMapping("/arduino")
public class ArduinoRestController {

    private SerialPort serialPort;
    private OutputStream outputStream;
    private InputStream inputStream;

    private String LedLog;
    private String TmpLog;
    private String LightLog;
    private String DistanceLog;

    @GetMapping("/connection/{COM}")
    public ResponseEntity<String> setConnection(@PathVariable("COM") String COM, HttpServletRequest request) {
        log.info("GET /arduino/connection " + COM + " IP: " + request.getRemoteAddr());

        if (serialPort != null) {
            serialPort.closePort();
            serialPort = null;
        }

        //Port Setting
        serialPort = SerialPort.getCommPort(COM);

        //Connection Setting
        serialPort.setBaudRate(9600);
        serialPort.setNumDataBits(8);
        serialPort.setNumStopBits(0);
        serialPort.setParity(0);
        serialPort.setComPortTimeouts(SerialPort.TIMEOUT_READ_BLOCKING,2000,0);

        boolean isOpen = serialPort.openPort();
        log.info("isOpen ? " + isOpen);


        if (isOpen) {
            this.outputStream = serialPort.getOutputStream();
            this.inputStream = serialPort.getInputStream();

            //----------------------------------------------------------------
            //수신 스레드 동작

            Worker worker = new Worker();
            Thread th = new Thread(worker);
            th.start();


            return new ResponseEntity("Connection Success!", HttpStatus.OK);
        } else {
            return new ResponseEntity("Connection Fail...!", HttpStatus.BAD_GATEWAY);
        }


    }

    @GetMapping("/led/{value}")
    public void led_Control(@PathVariable String value, HttpServletRequest request) throws IOException {
        log.info("GET /arduino/led/value : " + value + " IP : " + request.getRemoteAddr());
        if (serialPort.isOpen()) {
            outputStream.write(value.getBytes());
            outputStream.flush();
        }
    }

    @GetMapping("/message/led")
    public String led_Message() throws InterruptedException {
        return LedLog;
    }

    @GetMapping("/message/tmp")
    public String tmp_Message() {
        return TmpLog;
    }

    @GetMapping("/message/light")
    public String light_Message() {
        return LightLog;
    }

    @GetMapping("/message/distance")
    public String distance_Message() {
        return DistanceLog;
    }




    //----------------------------------------------------------------

            }catch(Exception e){

            }


        }

그리고 실행시켜 포트를 연결시키면 각종 값들이 출력되는 것을 확인 할 수 있다. 

 

 

 

인텔리제이로 서버를 연결시킨 상태에서 visual studio로 간다.

 

폼을 만들어 주고 코드들을 작성해본다.
