Is it possible to ad an Arduino?

@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.

@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
