Interrupt on change for IR input - is it a good way to go

[ardhuru]

only issue i see is the like most IR receivers , they tend to pickup rubbish and send random pulses , thus false triggering an interrupt check ,

Do you have a resistor in series (100 ohms should be okay) with the module's Vss and the +5 volts, and a capacitor (10 uF) across the module's Vss and Ground?

These two would help tremendously reduce the noise you refer to.
