Please any one can help me to make listing program with HCSR-04 for measuring speed
I would start with the examples that are included in the library. The Arduino IDE has an SR04 library you can easily install and use
Speed is distance over time.
Take a measurement of distance (distance1). A fixed amount of time later (fixed_time), take another distance measurement (disyance2).
Speed = (distance2 - distance1)/fixed_time.
