“This is a second project in series on coronavirus protection from TinkerGen. You can find the first article here. We firmly believe that with humanity’s collective efforts, current epidemic will soon come to an end. But even after COVID-19 has passed we should remain vigilant and keep the good habits we (hopefully) developed during these tough times. The previous article was focused on using Micro:bit to pay more attention to us unconsciously touching our faces and by doing that prevent the spread of germs. In this article we’ll design and build a simple, yet powerful weapon against microbes - a little device, that we can use to measure the amount of time we spend washing our hands.
