Is it possible to ad an Arduino?

[sdetweil]

@Shinji0912 add

debug:true

to the config section of the arduport module def in config.js

Ok so like i said it starts now , but the ArduPorts module still says : “waiting for connection”
and i added the

debug: true,

line. And for some reason Ctrl + shift + i does nothing for me except that the radeon software takes a screenshot… so heres the full console log :

pi@raspberrypi:~/MagicMirror $ 

EDIT:
Seems like it can’t find the Arduino but via NodeRed i can see it is sending Informations which the Pi is able to read.

[sdetweil]

@Shinji0912 it found the Arduino and then died when the data arrived on wrong format

[Shinji0912]

@sdetweil Ok … so is it the Arduino sketch that is the problem and if yes what should i change?

[sdetweil]

@Shinji0912 says json.parse failed. are u sending json formatted data as required?

[Shinji0912]

@sdetweil Im not sure about that …
Like i said im a reallyyy bloody newbie… sry :C

#include 
#include "DHT.h"

#define DHTPIN 2
#define DHTTYPE 11

DHT dht (DHTPIN, DHTTYPE);



void setup()
{
  Wire.begin();
  Serial.begin(9600);
  dht.begin();
}
  

void loop()
{
  delay(2000);
  float temp = dht.readTemperature();
  float rel_hum = dht.readHumidity();
 

  if (isnan(rel_hum) || isnan(temp)) {
    Serial.println(F("Daten vom Sensor konnten nicht gelesen werden!"));
    return;
  }
  float hif = dht.computeHeatIndex(rel_hum);
  float hic = dht.computeHeatIndex(temp, rel_hum, false);

  Serial.print(F("Luftfeuchtigkeit: "));
  Serial.print(rel_hum);
  Serial.print(F("%  Temperatur: "));
  Serial.print(temp);
  
  Serial.print(F("°C "));
  
  Serial.println(F(""));
}

this is the arduino code

When i tried to rewrite the given code by ArduPorts it didn’t even showed me the temperature in the SerialMonitor this was the sketch ;

volatile int32_t m_counter = 0;
bool WasStarted = false;

static const char *pcDHT11Prefix = "[sensor:DHT11:";
static const char *pcPostfix = "]";

void setup() {
  Serial.begin(9600);
  while(!Serial);
  
  Serial.println("[status:setup:starting]");
  Serial.println("[sensor:DHT11:11]");
  
  int test = 1;
  m_counter = test;

  if(test > 1) {
    WasStarted = false;
    Serial.println("[status:setup:failed]");
    return;
  }
  
  delay(3000);
  WasStarted = true;
  Serial.println("[status:setup:started]");
  delay(100);
}

void loop() {
  Serial.print(m_counter + 11);
  Serial.println(pcPostfix);

  if(m_counter % 3 == 0) {
    delay(1000);
    Serial.print(pcDHT11Prefix);
    Serial.print(m_counter + 11);
    Serial.println(pcPostfix);
    delay(2000);
  }
  if(m_counter >= 60) m_counter = 0;
  m_counter++;

  delay(1000);
  
  }

EDIT 2 :

This is what the Arduino SerialOutput looks like in NoteRed
( using the Rewritten ArduPorts Sketch)
:

[sdetweil]

@Shinji0912 use one of the online json validators to check your messages

[Shinji0912]

@sdetweil

[sdetweil]

@Shinji0912 only what u send(println) not the whole sketch

json, all text strings must be in double quotes
Serial.print(pcMQ2Prefix);
Serial.print(m_counter);
Serial.println(pcPostfix);
sample shows sketch sending sensor info
