Description:

In the kit Automatic Light Controller using 7806 needs no manual operation for switching ON and OFF when there is need of light. It detects itself whether there is need for light or not. When darkness rises to a certain value then automatically light is switched ON and when there is other source of light i.e. day time, the light gets OFF. The sensitiveness of the light can be adjusted. The circuit thus saves the electrical power as well as man power. The principle involves the detection of the intensity of light with help of LDR which changes the value of resistance across it on the basis of light. This principle is used in various applications. – PowerPoint PPT presentation
