Non-contact AC Voltage Detector Circuit Diagram
Let’s create a Non-contact voltage detector/tester circuit. Around five years ago, I taught my son to build this circuit. And now my daughter also wants to make it. It is a very useful circuit, uses to detect if the AC main wires or any electrical appliances have electricity in them or not. Read more
