USING AN LDR SENSOR WITH ARDUINO. Contribute to scorpHQ/LDR-and-Arduino development by creating an account on GitHub.

In this project we are making a Light Sensor using LDR with Arduino to control a light bulb/CFL as per light condition of the room or outside area.

This is an Arduino library for interfacing with an LDR (Light Dependent Resistor) sensor. With this library, you can easily read the analog value of an LDR sensor connected to your Arduino board.

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 detect light or dark and monitor the output of LDR ...
