Arduino to breadboard with LM35 temp sensor I have moved the MCU of the Arduino to a breadboard using these steps https://www.arduino.cc/en/Main/Standalone then interfaced it with an LM35 temperature sensor to the ADC0. But I can't get proper values from the LM35. I think it's because of the Aref or AVcc. Both are just connected to +5? 
Here is my code:

float tempC;
float reading;

void setup()
{
    Serial.begin(9600);
}

void loop()
{
    reading = analogRead(0);
    tempC = (reading * 0.4882815) + 5;
    Serial.print(tempC);
    delay(1000);
}


I get hex values and sometime high values. What to do with Aref and AVcc?

EDIT: I get values like these

Check the baud rate of your serial monitor matches what you have set in your setup() function.  In the above code that is 9600.  If the baud rate is incorrect you typically get rubbish output in the serial monitor.



You may also want to change the Serial.print(tempC) to

Serial.println(tempC,2);


To get some decimal places.

As for the circuit ~




You don't need ARef connected. 
The LM35 VCC should be connected to Arduino 5V 
The LM35 GND to Arduino Gnd (any of them) 
Finally LM35 signal (Vout) to Arduino A0.
