Circuit Description The LDR is configured in a voltage divider circuit to provide analog input to the Arduino. As light intensity changes, the voltage at the analog pin (A0) varies accordingly. The ...

How It Works The LDR is connected to a voltage divider circuit to produce an analog signal proportional to the light intensity. The analog signal is read by the Arduino via pin A0. The program ...
