Is it possible to ad an Arduino?

[Shinji0912]

Hi, for school we need to build a project using an Arduino.
For me the Arduino itself is boring thats why i decided to build a MagicMirror using Raspberry Pi and i wanted to integrate functions from Alex, different Sensor-stats like Temperature and the PIR
But everything i tried didn’t worked and now im Wondering if it’s even possible to connect both.

Sensors i have and want to use :
DHT11, for Temperature in Room,
HC-SR501, for Timeouts when not standing infont of it
ESP8266 ESP-12E, to Connect to the Alexa

Im Using a Raspberry Pi3
and an Arduino Uno R3 with the ELEGOO Ultimate Starter kit and a few other modules.

i would really appreciate if someone helps me and if you have good ideas to what i should add to get a good grad xD i would really appreciate it aswell.

This is my Current Config :

							// Default, when address config is left out or empty, is "localhost"

EDIT:
And oh before i forget i would like to add some w2812b RGB Strips

@Shinji0912 there are a bunch of arduino modules on github

google search

mmm-arduino github

some are general (arduport)
some are more specific MMM-temphumidity

@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.
