Using NTC with Arduino
Arduino UNO has 6 analog input pins. We can analyze signals from 0 to 5 Volts.
In this application we will use one analog input terminal. The terminal we will use for the analog input is the A0 terminal.
The voltage at the analog inputs has a numerical value between 0 and 1024. This is a digital value. For example, if the input voltage is 2.5 Volts, its equivalent would be 512.
What else can be done with NTC. We can make a fire alarm system of a house or a workplace with 6 NTCs that we will connect to 6 analog inputs of Arduino UNO.
We used led as a warning light, but we can also use a buzzer.

Arduino Codes:
void setup() {
// Red leds -------------------
  pinMode(13, OUTPUT);
  
}
void loop() {
  
int pot_in = analogRead(A0);// NTC INPUT
// pot_in 0------>1000
if(pot_in>600){
    digitalWrite(13,HIGH); delay(100);digitalWrite(13,LOW);
}
}
