I need a velocimeter to measure the wind speed using an Arduino Mega 2560. - As sensor I have an anemometer that send a positive pulse every 220mm (or 2 pulses per revolution where the radius is 70mm). - I'm using the Arduino Mega 2560 with Ethernet Shield. On Ethernet Shield I'm only using the SD card. - I'll write to a file (SD Card) the current wind speed every 10s so this is the sample rate. - AttachInterrupt (Rising) must be used once I'll do a lot of things between the sample of 10s. - I'm using pin 2 (Servo Motor), and also pins 36 to 53 as I/O's. - Please only bid if you KNOW how to use interrupts and keep time to process other things. - Less dan 1 day to do it. You need to let me know the pin to be used and send me the code. The payment will be done if the code work.

Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. I can help you with your deal and since im new one here I can do it cheaper then anybody. (autopromotion^)) As I understand, you want to turn on interrupt for measure duration only. Then turn it off and turn on again to do next sample in 10 sec. And so on. Right? Absolutely no problem.

I teach arduino classes at my local Maker Lab, I can help you figure out how to do this yourself. It isn't a difficult thing to learn, Message me and I will point you in the right direction.

I have done a project like this one. My old project was a water flowmeter with reed relay. I would like to know more about your sensor and project. Unless you must especially use interrupt i recomend alternative methods because of timing issues and robustness by experience.
