For this Keyhole Light Circuit, we need a light sensor to detect the light condition and some circuitry to control the Light sensor. We are using a LDR to get control according to the intensity of ...

I love all about electronics, circuit diagrams and crazy projects that can help us achieve almost everything our mind can conceive. I created this website and I want to invite you to participate in ...

The circuit of light detector is very simple and easy to build with very few components. As you can see in the LDR circuit diagram, it can be a distinguished as two smaller circuits; a) Voltage ...
