    2020-5-19 · Working Principle of Darkness Detector. First, we will start with the 555 timers. It is configured in astable mode. When there is light falling into the LDR, its resistance becomes very low. In this condition, the voltage divider will produce almost 0V from its output formed by 1 MΩ resistor. In this situation, the 555 timer IC will be reset.
