🔘ABOUT THIS VIDEO ..
In this video I'm going to explain.. how to make a automatic On-Off Bathroom light using PIR motion sensor. And I make it very simplely & minimum components. And it's also a 100% warking model . In this 4017 project, I have shown how to make motion sensor light switch using CD4017 & PIR sensor for the washroom.
