DIY LED Night Light CD-01 Light Control Kit Electronic Learning Kit
Feature:
Control circuit part is using photosensitive characteristic of the photosensitive resistor R4 and triode conduction condition to control light emitting diode ON and OFF.It doesn't work during the day， night light automatically at night， can be used in the bedroom and other places of need light lighting at night.This circuit can be controlled according to the strength of the light to turn on and turn off， and has the advantages of power saving， energy saving， high stability.
This is an electronic DIY kit， you need to have some electronic knowledge and ability.As shown in FIG instructions and schematics， package does not includes EN instruction.
