hey guys, I hope this is the right place to post this.
Basically I am going through Sparks Fun tutorial #7, reading temperature off a TMP36 sensor.
My problem is that I am reading very low values on A0 from the sensor. I hooked it up correctly and when I read the voltage off the sensor with a multimeter, I get 520mV-550mV, which corresponds to a temperature of about 12C-15C (my heating is broken so that could make sense).
Do you guys know what the problem is? If it’s not the setup and not the sensor, why would the board read in really low values from A0? I am using an Arduino Uno, the relevant part of the code is below, atm the raw values on the A0 pin are close to 0, they do go up when I hold and warm the sensor.
const int temperaturePin = 0; Serial.println(analogRead(temperaturePin));
