Description
Ajdustable Timer Automatic Hand Washing Module
The project is about automatic hand washing module that has an adjustable pot for changing the timing. I built it to replace the manual hand washing bucket in order to help minimizing contact with infected person. This will go a long way to prevent the spread of the covid19 pandemic.
