Connecting two Arduinos via I2C while I2C Pins A4/A5 are already in use I have the following problem:
Since the BH1750 Sensor only supports two different I2C adresses, but i need to use 6 of those sensors, i wanna use 3 arduinos, 2 nanos, 1 uno and send the data from the nanos to the uno. Problem is that the I2C bus is already in use and while trying to send data, it does not work properly.
Is this even possible? When trying it out, i can't get anything correct



Update:

That's what i tried now:

Results i get are still not correct



#include &lt;Wire.h&gt;
#include &lt;BH1750.h&gt;

// This code will feature the use of 6 gy 30 light sensors

BH1750 active_sensor(0x23); // We will use this adress for stating the active sensor
BH1750 inactive_sensor(0x5C);

void setup(){

  Serial.begin(9600);

  // Setting the input pins for controling the addr pins of the modules
    pinMode(8, OUTPUT); 
    pinMode(9, OUTPUT); 
    pinMode(10, OUTPUT); 
    pinMode(11, OUTPUT); 
    pinMode(12, OUTPUT); 
    pinMode(13, OUTPUT);

    digitalWrite(8, LOW);
    digitalWrite(9, LOW);
    digitalWrite(10, LOW);
    digitalWrite(11, LOW);
    digitalWrite(12, LOW);
    digitalWrite(13, LOW);


  // Initialize the i2c bus
  Wire.begin();

 // Here we will set the mode of the module
  if (active_sensor.begin(BH1750::CONTINUOUS_HIGH_RES_MODE)) {
    Serial.println(F("BH1750 Advanced begin"));
  }
  else {
    Serial.println(F("Error initialising BH1750"));
    Serial.println("Problem on 1");
  }
}

void loop() {  
  get_values();

}

void get_values(){
  int i;
  Serial.println("----");
  for(i = 8; i&lt;=13;i++){
    digitalWrite(i,HIGH);    
    delay(50);
    int lux = 0;
    lux = active_sensor.readLightLevel();    
    Serial.println(lux);    
    delay(50);
    digitalWrite(i,LOW);
    delay(150);
  }
}
Use the ADDR pin as a chip select. Pull both pins high normally. When you want to talk to one, pull the ADDR pin low and use the ADDR = 0 address to talk to the selected device. Then you can have all 6 connected to one Arduino.
