Hi,

Thanks for the replies so far on this topic.
From what I can understand My idea for using encoders wont work due to the lack of interrupts.

Is that right ?

I remember reading the Atmel 328 Data sheet and it mentioned that besides there being EXTERNAL interrupts, of which I believe there are 2 which at present are being used by the wind speed and rain gauge sensors, there are also INTERNAL interrupts, up to 20 if not more (23).
So I went to the Arduino web site and did a search "PCINT" which I believe are the INTERNAL interrupts.
Attached is what found about them, I am thinking if these can be used it would be a big help not only for my project, but for the WeatherDuino project as well.

I look forward to your opinions.

Regards
