Question

In bright light, the total resistance of the buzzer and the LDR is 400 ohms. What is the current in the circuit?

Answer 1

Answer:

The LDR gives out an analog voltage when connected to VCC (5V), which varies in magnitude in direct proportion to the input light intensity on it. ... When there is sufficient light in its environment or on its surface, the converted digital values read from the LDR through the Arduino will be in the range of 800-1023.
