Delay a part of the void loop I have two different programs written for my Arduino. One checks the room temperature every 5 seconds. The other one looks for IR remote signals.

I would love to combine those 2 programs, yet the problem is the delay from the room temperature sketch.

If I would combine them. it means my IR script won't be working for a full 5 seconds (because of the delay of the room temperature script) then it will be able to receive a fraction of a second and then the temperature sketch goes again.

#include &lt;IRremote.h&gt;

int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);
decode_results results;
int led = 12;
const int inPin = 0;

void setup() {
  pinMode(led, OUTPUT);
  digitalWrite(led, LOW);
  Serial.begin(9600);
  irrecv.enableIRIn();
}

void loop() {
  int value = analogRead(inPin);
  float millivolts = (value / 1024.0 ) * 5000;
  float celsius = millivolts / 10;
  Serial.println(celsius, 1);
  delay(5000);
  if(irrecv.decode(&amp;results)) {
    //this checks to see if a code has been received
    if(results.value == 0xFF6897) {
      //if the button press equals the hex value 0xC284
        digitalWrite(led, HIGH);
        // turn the LED on (HIGH is the voltage level)
        delay(1000); // wait for a second
        digitalWrite(led, LOW);
        // turn the LED off by making the voltage LOW
        delay(1000); // wait for a second//do something useful here
    }
    irrecv.resume(); //receive the next value
  }
}


Does anyone know how to keep the IR part active and the temperature measure every 5 seconds, and do this simultaneously?

Or do I need another Arduino?
does anyone know how to keep ...


think about ways to conditionalize execution on time elapsed. I showed a short while ago ways to construct a software timer and you may want to look into that.
