How to control termometer in Arduino

Today I'm going to show you how to control termometer. Firstly you will need to connect terometer to Arduino.

Now open your arduino! =)

void setup() //setup function
{
  Serial.begin(9600); //install Serial output
}

int checkTemp() //read temperature function
{
  float voltage = 0; //float variable for volts
  float celsius = 0; //float variable for celsius
  float sensor = 0;  //float variable for sensor
  
  sensor = analogRead(0); //read from analog input 0
  voltage = (sensor * 5000) / 1024; // convert raw sensor value to millivolts
  voltage = voltage - 500; // remove voltage offset
  
  return (voltage / 10); // convert millivolts to Celsius and return result
}

void loop() //loop function
{
    Serial.println(checkTemp()); //print result of checkTemp() function
}

Ok, now upload your code. And press tools->"Serial Monitor" or Ctrl + Shift + M. Done!
