Dear Martin,

For the workshop I would like to use Arduino to make a pressure sensor on footprints that when stepped on would make a heavy sound liken to a heavy footstep with an echo. I would also like to be able to regulate the volume so sound loudly if a light weight person step on it and softer when step on by a heavier person. The footprints would be either cut out from metal sheets or a polyurethane cast of  my feet.
Best,
