  • LIGHT DETECTOR Circuit - 555 Timer Circuits

    2020-5-13 · Here we have explained a Dark/Light Detector using 555 Timer & LDR (Light Dependent Resistor) which senses the light in surroundings and if it does not find the light, it triggers the IC and glows an LED attached with the circuit. In place of LED we can also use a buzzer or speaker to use it as dark detector alarm.
