Thanks for the speedy response! Attached is a picture of my setup. FYI, I had to use a couple of 10k ohm resistors in parallel to make a 5k and a couple of 10ks in series to make 20k. Regarding INT0 = pin 2, it all makes sense now. Looks like I'd only changed the #define enablelRrx under "//def...

I got it working and just had a couple of comments/questions: I think there's a typo in sketch. This line refers to pin 2 but pin 0 is being used just after the open bracket:...
