I'm fairly new to Arduino, so I bought an Uno to start tinkering. My first project is a 434mhz weather station receiver. I've setup the hardware via the Practical Arduino book (http://www.practicalarduino.com/projects/weather-station-receiver) but I'm starting to look at the sketch and I'm a little confused about the use of interrupts on the Uno. The Practical Arduino guide suggests using input pin 8, calling it the "input capture pin" that has capabilities that other digital pins don't have. But other sketches I've seen use pin 2 (and use interrupt 0 code with attachInterrupt).
Should I use pin 8 and all of the macros necessary in the sketch or is it possible to just use pin 2 with a simple attachInterrupt() call?
Thanks!
