                                                Wee Can Save energy puting A relay enves de a LED and A lamp circuit to save energy!!!
                                                                  
                                                Green constest!!! I Love Nature!!!

Supplies:

Step 1: Turn and Use!!!

puT tHE bATTERY on The Jack An Automatly The LED Will Turn ON .When You PUt The LDR On LIgth The LED Will BE OFf!!

Step 2: KNow How It Function!!
