Light Sensor and Darkness Detector Circuit using LDR | 555 Timer Project #16

A tutorial on how to make a light sensor circuit and dark detector circuit using 555 timer IC and a few other electronics components. When this circuit is configured as a light sensor circuit, it turns ON the output whenever light around the LDR is more than a certain amount (threshold). This threshold can be adjusted by using a potentiometer. Similarly, when this circuit is configured as a dark sensor circuit, it turns ON the output whenever light around the LDR is less than a certain threshold. So the behavior is opposite to that of light sensor. This arrangement can be used in automatic street light circuits to turn the light ON and OFF automatically depending on how bright it is.
