RE: Ultrasonic range finder - BULK BUY?

[ian.bird@xxxxxxxxxxxxxx]

I don't think HV will care that the units values are changing
constantly.=20
As you say you will read them when you decide it is best and go from=20
there. You may ignore them most of the time for example if the Garage door=
=20
is closed.

I guess I could always read the values into another variable several times=
=20
a second or at a rate that doesn't cause a problem and them use that=20
instead?
