/* *How to operate LDR using Arduino uno (with analog input) *This code discribes that how an Light dependent resistor can be operated with analog input using Arduino Uno.

Arduino code example for using LDR's on a model railroad layout This approach uses (at least) 3 LDR's between the rails and all are used for detection purposes.

Dark sensor Light and dark detection using an LDR For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by placing jumpers. We’ll be using this module to ...

Arduino is a very popular open-source platform and Arduino UNO is one of the most loved microcontrollers among electronics hobbyists worldwide. It consists of a physical programmable circuit board and ...

The required intensity of light is obtained by taking the average of all four LDR's and compared with the reference intensity of the light as specified by the user. Accordingly the whole intensity of ...
