[3/Love-o-meter] it seems TMP36 doesn't work (volts: 0.00 ; degrees: -50.00)

Any idea what i'm doing wrong?

Please post your code.

Should be the same as in the manual.

const int sensorPin = A0;
const float baselineTemp = 20.0;

void setup(){
  Serial.begin(9600);
  for(int pinNumber = 2; pinNumber < 5; pinNumber++){
    pinMode(pinNumber, OUTPUT);
    digitalWrite(pinNumber, LOW);
  }
}


void loop(){
  int sensorVal = analogRead(sensorPin);
  Serial.print("Sensor Value: ");
  Serial.print(sensorVal);
  float voltage = (sensorVal/1024.0)*5.0;
  Serial.print(", Volts: ");
  Serial.print(voltage);
  Serial.print(", Degrees: ");
  float temperature = (voltage - .5)*100;
  Serial.println(temperature);
  
  if(temperature < baselineTemp){
    digitalWrite(2, LOW);
    digitalWrite(3, LOW);
    digitalWrite(4, LOW);
  }
  else if(temperature >= baselineTemp+2 && temperature < baselineTemp+4){
    digitalWrite(2, HIGH);
    digitalWrite(3, LOW);
    digitalWrite(4, LOW);
  }
  else if(temperature >= baselineTemp+4 && temperature < baselineTemp+6){
    digitalWrite(2, HIGH);
    digitalWrite(3, HIGH);
    digitalWrite(4, LOW);
  }
  else if(temperature >= baselineTemp +6){
    digitalWrite(2, HIGH);
    digitalWrite(3, HIGH);
    digitalWrite(4, HIGH);
  }
  delay(100);
}
