Today I'm going to tell you how make a smart tap. This smart tap is very use full to us in these day, because we live with the Corona or Covid 19 virus. So it is a very important health advice to wash your hands. When we wash the hands we have to touch the tap so this virus spread from the tap. This tap is a solution for that problem.
when we go near to the tap it detect somebody is here and it opens the solenoid valve so water is come out. When we go from there it detect nobody is there and it close the valve so water can't come out. Also we didn't want touch the tap. In this tap no danger to spread any virus.
