![Светлосни сензор](picture_library/SvetlosniSenzorSvetliDanju1.jpg) |
When light falls over the light-dependent resistor transistor starts conducting and LED diode lights |
![Светлосни сензор](picture_library/SvetlosniSenzorSvetliDanju2.jpg) |
When it gets dark or you cover light-dependent resistor, then transistor doesn't conduct and LED diode doesn't light |
It lights at night |
