what code can i use to check the temperature every 5 sec with lm35 ?

[Reply #1 on:]

Code:

const unsigned long interval = 5000;           // Interval between samples, in milliseconds

void setup() {   
}

void loop() {
    static unsigned long previousMillis = 0;
    unsigned long currentMillis = millis();
 
  if(currentMillis - previousMillis > interval)  {
     previousMillis = currentMillis;
     // The code in this block is executed every 'interval' milliseconds

  }
}

Great  that is "temperature reading without delay()"
