I have come across some Andruino Sensors like Motion, Light and all recommend to be connected to pin 2 or 3 on Andruino Uno board which are interrupt pins. This is especially true if you are looking for HIGH or LOW values. Why is that to be connected to interrupt pins?
One example would be is I used CC3000 Wifi Breakout and Motion sensor. Both were in fight to occupy the interrupt pin 2. I have seen the Motion sesnor not working correctly after getting it's signal hooked to Pin 4[It has pull up resistor enabled]
What should I do if i need to hook up more sensor which uses the limited interrupt pins and how should i handle the above scenario?
