Getting People to Wash Their Hands More!


for our school project, want people wash hands more after having used bathroom.
we attempting use break beam sensors , polaroid electrostatic transducer detect movement
of user. when not wash hands, sound triggered humiliate them , make
an awkward situation.

our setup: arduino uno, light sensor, speakers, polaroid electrostatic transducer, bicycle reflector, laser pointers.

our strategy: setting 2 laser pointers separating sinks(to detect 1way direction) , toilets , proximity sensor around sink.
                   once comes out of toilet, break beams first triggered, proximity sensor if he/she
                   uses sink. but, if break beams triggered , not proximity, sound actuated.

we new arduino , don't know how set specificities, code. if can out or provide better way go this, appreciate it. thanks!

interesting project.
not dampen enthusiasm, if found of in bathroom @ work find kind of creepy.  wonder if taking pictures...

one way make sound adafruit wave shield.  http://www.adafruit.com/products/94
