Light -dependent switch kit - B1004
Description
Light -dependent switch kit - B1004
A simple circuit which has many uses, e.g. Automatic ( light dependent ) circuits of lights in shop windows or spaces, depending on the desired brightness level for alarm systems , production control systems, etc. The circuit operates with a photo resistor which changes its value according to the amount of light received and three transistors, the output from the LDR resistance amplify signals and switch a relay.
