Interrupt Pins in Arduino Uno

Using Arduino Programming Questions

Hi all XD

I need help about Rover 5 encoders , I have Rover 5 with two encoders and each encoder has two signals , signal A(White wire) and signal B (yellow wire ) and I want to use interrupt method (the best , which don't miss count) to count the number of counts or ticks for both encoders , I had Arduino Uno board and as known that Uno has only two interrupts pins (pin 2 and 3) and my encoders has for wire , two wire for each encoder . so how could I deal with this problem ?? and is there any method to count the number of encoder counts by used just signal A ?

thank a lot.

The Atmega328 has pinChange interrupts that work on several pins. See Nick Gammon's web page and study the Atmega328 datasheet.
