9V battery LDR sensor 50K, 1K Ohm resistor BC547 Transistor So when sufficient light falling on LDR the resistance of LDR in very low, as a result all current is flowing from resistor R2 AND LDR so ...

In this article we will see how can we build a darkness sensor by using LDR sensor. This sensor detect light falling on it and change it resistance accordingly. This change in resistance of LDR detect ...

We have explained the need of LDR in our circuit in the ‘working of the project’ given later in the project. We previously made many Circuits using LDR, which use LDR to automate the lights according ...

Through a set of webpages, users can remotely control a light intensity sensed through a Light Dependent Resistor (LDR) sensor connected in an arm of a configurable Wheatstone Bridge (WB), whose ...

In the past few years, the technologic evolution of communication and information systems had a major impact in our lives. In education, this evolution broke some geographical barriers, facilitating ...
