For this, we need a light sensor ... LDR to automate the lights according to requirement. As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k resistor. The voltage ...

If in the dark, the sensor has a high resistance — think several thousand ohms or mega ... diagram that can be switched as the light and dark sensor… This example uses an LM358 dual-operational ...

We have used LDR sensor to build many light controlled applications: The circuit diagram to connect BH1750 Light sensor with Arduino is shown below. I2C communication pins SDA and SCL of BH1750 are ...
