hello,
I am workng on an ultrasonic distance meter.it is based on this project:
**broken link removed**
the minimum distance that my circuit shows is 279mm,I changed the delay of minimum distance in software but I still have 279mm min distance instead of a smaller output .
now my question is:
Is this limitation due to hardware(my ultra sonic sensors) or I should change my software in order to measure shorter distances?
