As found in the schematic of the generic PIR motion detector module, one pin of the LDR goes to ground rail (0 V ... on-board voltage regulator, and Arduino IDE compatibility. The code is an Arduino ...

In that case, this Arduino-based smart light might be more your cup of tea. The idea behind this project is to build a lightbulb controller using a light-dependent resistor (LDR). The LDR ...

you need to program Arduino to read a sensor and direct the data to the Serial Port. Here, a standard light-dependent resistor (LDR) is used as an analog input sensor and directs its output to the ...
