Stanley:
Dear Tim,Are you able to add the option to have the distance measurement/pulse width based on LOW signal instead of HIGH signal ? With this, the URM37 passive PWM mode should work with the NewPing library...
Thanks
It would be possible. But would be like shooting in the dark without an actual sensor to test with. There could be a host of other problems. From your testing, is it sending out a single low pulse or is it pulses as the documentation states?
