Is it possible to ad an Arduino?

Shinji0912

@sdetweil Oh ok , the school told us to buy the Uno R3 and it’s the first one i’ve used so far ^^

sdetweil

@Shinji0912 don’t see ttyUSB0
are there any message on the console where u start mm? npm start? or pm2 logs --lines=???

??? is a number, default is 15

Shinji0912

@sdetweil Not as far as i can see.

sdetweil

@Shinji0912 so, I would use the linked examples outside mm to make sure it works

Shinji0912

@sdetweil Ok so i have installed Serialport on the Pi and told the arduino to digitalwrite 10 but how to i let the Pi read 10?

sdetweil

@Shinji0912 Google , there are many examples

Shinji0912

@sdetweil , @wishmaster270

Ok , so now i got the Arduino to communicate with the PI via usb, (i got the right Portname using NodeRed). This is the current Arduino Script :

#include <Wire.h>
#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(""));
}

Some things are in german so dont be suprised ^^

and via NodeRed i know that it is working and the Pi is currently reading the data.

My issue now is that my Config.js isn’t working anymore after installing ArduPorts ??

This is the current config :

i don’t know what to do now :C i thought i had it working this time finally …

EDIT :
Found the mistake i’ve written “ture” not “true” fml…

EDIT 2 :
But it’s still not working as i want it to it still says :“Waiting for Connection” on the Arduport module when launching the MagicMirror.

sdetweil

@Shinji0912 and u did the npm install in the arduport module folder?

Shinji0912

@sdetweil yes i did .-.

sdetweil

@Shinji0912 ok, need to see the console logs

from nom start or pm2 logs

and the developers window ctrl-shift-i on the keyboard, then select the console tab and scroll up to see any errors.

u can also filter messages by.module, by adding part.of the module name to the filter field, ardu for example

Shinji0912

@sdetweil Ok currently im not at home but will upload when home ^^

sdetweil

@Shinji0912 add

debug:true

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

Shinji0912

This post is deleted!

Shinji0912

@sdetweil

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 :

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)

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