What's that methodology.
To not use delay(). It appears that you didn't even look at the example.
Just took a look at it here: http://www.arduino.cc/en/Tutorial/BlinkWithoutDelay
I'm not trying to blink an LED. The code i posted here is just an example to demonstrate the problem I'm facing in my original program.
I'm trying to use both external interrupt pins to select two different modes (warm, hot) for a heating device that's reading off a temperature sensor. So i basically have two push buttons wired to pins 2 and 3 on the Uno to interrupt the processing cycle when i need to heat water inside the heating device to a specific temperature (two heating targets: warm and hot).
The problem is when pushing those switches, they bounce every now and then triggering interrupts that are not supposed to be triggered, so the ISR is executed more than once for a single push (theoretically)..
Thanks for the fast replies, Paul
