IC can't sample the A/D converters that quickly. As long as you're generating a nice squarewave you could connect it to one of the input capture pins and write a custom interrupt routine to maintain the count. --Chuck (...) (24 years ago, 10-Sep-00, to lugnet.robotics.handyboard)

hi. you can certainly tap the 9.6v batt output to power the sensor (use J13), but make *sure* that the sensor does not put out more than 5v, or you'll blow your analog inputs. if you're not sure, put a 1K resistor in series with the sensor's output (...)
