It never ceases to amaze me how astoundingly slow sound is
compared to the speed of a computer.

| Hi, (...) since sound travels at about 333 m/s (depending on temperature and pressure), a meter takes 3 milliseconds. At the maximum range of 2.5 meters, times two that would be 15 milliseconds per reading. Cheers Jürgen (20 years ago, 6-Sep-06, to lugnet.robotics)
