next topic   Hello to all! i am new on this forum as i thought
it would be the best place to ask this question 8-)  im in a
need of an laser-sensor wich would recognise a soap bubble. what
do i need to search for? thank you all very much for the
answer!! :) :)   May you are on the wrong site...this is
exhibition....   ;)   Recognise a soap bubble in what way?  If
you shone the laser at a light dependent resistor (LDR) you
could tell when the beam changed - so if the only thing that
might pass is a soap bubble that'd do.  If you wanted to spot a
soap bubble instead of something else you'd have a bit more
trouble.  Go Up
