**Edit > when trying all the pins, I notice the SCL pin on the breakout board seems to give me the most accurate temperature reading, is this correct?

 

I'm playing with the breakout board and I have it connected to the Temperature brick.

I have the 5V and GND pin connected to the 5V and GND on my Arduino Leonardo board.  Now in my Temperature Sketch with Arduino, I am using the Analog pin A0 with my Arduino.  Which pin on the Tinkerforge Breakout board do I need to connect A0 to in order to get a correct temperature reading?

 

 

Here is my Arduino sketch...

 

    //TMP36 Pin Variables
    int sensorPin = 0; //the analog pin the TMP36's Vout (sense) pin is connected to
    //the resolution is 10 mV / degree centigrade with a
    //500 mV offset to allow for negative temperatures
    /*
    * setup() - this function runs once when you turn your Arduino on
    * We initialize the serial connection with the computer
    */
    void setup()
    {
    Serial.begin(9600); //Start the serial connection with the computer
    //to view the result open the serial monitor
    }
    void loop() // run over and over again
    {
    //getting the voltage reading from the temperature sensor
    int reading = analogRead(sensorPin);
    // converting that reading to voltage, for 3.3v arduino use 3.3
    float voltage = reading * 5.0;
    voltage /= 1024.0;
    // print out the voltage
    Serial.print(voltage); Serial.println(" volts");
    // now print out the temperature
    float temperatureC = (voltage - 0.5) * 100 ; //converting from 10 mv per degree wit 500 mV offset
    //to degrees ((volatge - 500mV) times 100)
    Serial.print(temperatureC); Serial.println(" degrees C");
    // now convert to Fahrenheight
    float temperatureF = (temperatureC * 9.0 / 5.0) + 32.0;
    Serial.print(temperatureF); Serial.println(" degrees F");
    delay(1000); //waiting a second
    }

The Temperature Bricklet uses I2C, there is no analog value comming from there. See the datasheet of the TMP102: https://github.com/Tinkerforge/temperature-bricklet/raw/master/datasheets/tmp102.pdf

 

Also: The supply voltage of the Arduino is 5V, the supply voltage of the TMP102 is 3.3V!
