[solved] alternative to forking the delay

Using Arduino Programming Questions
1

Hey folks, i very need your help.
So here a gas sensor, which need to be heated for 5 and 15 seconds, the data from sensor is taken at 4.985 and 14.985 seconds whilst given a +5 impulse, here how it looks:

digitalWrite(switch1,HIGH);
  digitalWrite(power,HIGH);
  delay(4985);
  digitalWrite(switch2,HIGH);
  delay(5);
//analogRead(..
  digitalWrite(switch2,LOW);
  delay(10);
  digitalWrite(switch1,LOW);
  delay(14985); 
 digitalWrite(switch2,HIGH);
  delay(5);
//analogRead(...
  digitalWrite(switch2,LOW);
  delay(10);

so the arduino actually stalls for 20 seconds, so i would most likely prefer to do some stuff in that 20 seconds, like, reading the second sensor or transfer to xbee etc..

obviously, i need to create like timer which will be checked every loop.
like

timer t1;

void setup() { t1.start}

void loop() {
heat();
if (t1 == 14.985) readthesensor()

And so on, hope you got me.
so i know that atmega has some global time which is count of processor ticks, but how can i convert it to seconds?
thanks for reading

Look at the blink without delay example in the IDE, without delay.

I repeat: without delay.

thank you:)
