Scrub your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end. A good way of timing 20 seconds of washing that doesn't require setting a timer on your phone, is to sing..... BTW Cool project.

Great work [mention:f5b888a3f4e840439117125bfd809ea0:e9ed411860ed4f2ba0265705b8793d05] and just the sort of simple project that can have a huge impact for little cost, I'm sure I never spend long enough washing my hands so might have to build one.

Can I however just point out from your video that if your hands were infected then touching the tap at the start and again at the end will undo much of your great handwashing. My only suggestion would be to use some of the soap lather on the tap halfway through to clean it or to use a tissue to dry your hands and then to close the tap off (disposing of it into a bin immediately).

Stay well [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-73dc038a-53e6-4b34-980b-a31d7bf51e9f/contentimage_5F00_1.png:16:16]

A good project. It might need some sort of box to protect the electronics from the water. A buzzer would also be useful. I was also interested in the PictoBlox concept as I have seen Scratch before but not known you can programme Arduino's with it.
