Light sensor 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 ...

Connect the A0 pin of the Arduino to the same column where the LDR and resistor is connected (Since the LDR gives out an analog voltage, it is connected to the analog input pin on the Arduino. The ...

Programming Arduino for interfacing BH1750 Light Sensor. The programming portion for using this LUX sensor with Arduino is very easy. Although there is a library available for this sensor, but we can ...

Using a smart street light system, we will save our electrical costs. In addition, smart street lights will control power more effectively by reducing the risk of the automated street light system ...
