Hi,Is anyone aware of any IC's that can be used to count the pulse from a hall effect sensor and whose count can be read via serial/i2c? I have found some IC's that provide a 4 bit digital output to represent its count, but i'm worried about losing input pins on the Arduino.If you've used any in the past, it'd be great to hear of anything!Cheers,Scott.

I didn't find such a chip when I last looked, so I've used a counter chip with parallel output and a shift-register to read its output... Is there a reason you can't just use pin2 or pin3 with an interrupt routine?
Yep, an ATtiny85/84.
No one mentioned the more obvious solution however, that all of the three AtMega timers can be configured to work as pulse counters.
I know, but I can't maintain my arduino on. So I need a "offline" solution to count for me.
EDIT: This is the thread, http://forum.arduino.cc/index.php?topic=69358.0, I didn't re read it to see if there are any details but I know that's what he did because I helped off line with it.______Rob
