Is it possible to ad an Arduino?

wishmaster270

@Shinji0912 Hi, I wrote a module which converts messages received at serial interfaces to notifications (https://github.com/Tom-Hirschberger/MMM-Serial-Notifications). I have two Arduinos connected to my Pi with gesture and distance sensors.

My temperature module (https://github.com/Tom-Hirschberger/MMM-Temperature) can receive notifications to update the values.
Edit: The notification feature is only available in the development branch at the moment. I will mere it to the master the next days.
There are examples integrated which show how to connect an esp32 board with WiFi to get temperature and humidity.
Currently I am working on a module which should use MQTT to control an WS2801 LED Strip. But this one is in a very early state and will take a while to develop.

@wishmaster270 Wow thank you very much , im completly new to this and first of all this helps me out very much and im going to try to make my own module showing an API from our school , is it okay if i ask you questions when i need help?
and btw. rrealllyy appreciate your help :)

@sdetweil I tried the “Arduports” one but for some reason it didn’t worked for the sensors im using ^^

sdetweil

@Shinji0912 u have to have code running in the Arduino sending the data, doesn’t just happen

Shinji0912

@sdetweil I know I’ve set it up but it didn’t worked.

sdetweil

@Shinji0912 seems pretty simple, connect serial port for arduino to serial port for PI…

arduino send 10
https://www.arduino.cc/reference/en/language/functions/communication/serial/write/
pi read 10
https://www.npmjs.com/package/serialport

u can test that without MagicMirror

@sdetweil Thats my Current Arduino code :

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);
  
  }

and i got the ArduPorts running on the MM itself

now it is running but always searching for the module … see Picture.

@Shinji0912 and the config for the port ??

              config: {
                portname: "/dev/ttyUSB0",

ls /dev | grep -i usb

I don’t see a ttyUSB0 on my pi4…
is that the right one on pi?

i would guess that is for a USB plugin serial port, not direct serial port…

I do have a /dev/serial1 (on all 3 of my pi devices, Pi0, Pi3, and Pi4)

Shinji0912

I have it plugged in on my Raspberyy Pi3 and the config on the Pi itself is

	modules: [
 {
	          module: 'MMM-ArduPort',
	          position: 'bottom_right',
              header: 'Arduino Sensors',
              config: {
                portname: "/dev/ttyUSB0",
                updateInterval: 1,
                animationSpeed: 1000,
                displayIcons: true,
                showDescription: true,
                hideLoading: false,
                hideWaiting: false,
                useColors: true,
                sensors: [
{
                        name: "DHT11",
                        description: "Temperature",
                        maxValue: 50,
                        maxFormat: "({0}°C) VERY HIGH",
                        highestValue: 30,
                        highestFormat: "({0}°C) HIGH",
                        highValue: 15,
                        highFormat: "({0}°C) NORMAL",
                        lowValue: 10,
                        lowFormat: "({0}°C) LOW",
                        lowestValue: 5,
                        lowestFormat: "({0}°C) VERY LOW",
                        minValue: 0,
                        minFormat: "({0}°C) OK"
                    },
]
            }
        },

and im not pretty sure what u want to tell me (im not an native english speaker) i come from germany

@Shinji0912 said in Is it possible to ad an Arduino?:

            portname: "/dev/ttyUSB0",

I think that is the wrong device name for the serial port on the pi. if you are using the gpio header pins

Ich denke, das ist der falsche Gerätename für die serielle Schnittstelle auf dem Pi. wenn Sie die GPIO-Header-Pins verwenden

Shinji0912

@sdetweil Im not using the Gpio header pins i have the Arduino connected to the Pi using usb?

sdetweil

@Shinji0912 i have never seen arduino connected via USB… none of my arduino devices have USB plugs

did u check the available device names on your pi?
from a terminal window do

ls /dev | grep -i usb

@Shinji0912 this is my arduino experience

Shinji0912

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

@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
