Interrupts on the Arduino NG
Does the atmega8 arduino NG have interrupts?-


Page 1 of the datasheet:



Yes, it has interrupts.




  just need one interrupt.


Page 46 of the datasheet:



It looks like you have 19 of them.




  regarding interrupts atmega8 is different168 there-so that may imply the the same code wont work -and I couldnt find any examples when searching


Try using the Arduino libraries. If that doesn't work post your code.
