^ ay mas maganda nga yan...

pero pinapakita ko lang sana na kakailanganin ng LDR para magawa yung circuit.

nga pala, ang night lamp ko (takot kasi ako sa dilim!!!!

), binili ko lang sa handyman. may LDR at isang bright LED. lagi lang yun nakasaksak sa outlet. tapos kapag madilim na sa kwarto, umiilaw yun. during day time, wala talgang ilaw. pero kapag gumabi na, syempre didilim, iilaw ng yung LED. tapos naman kapag pinailaw na namin yun florescent, humihina lang yung liwang ng LED. meaning, kailangan pa ng mas maliwanag ng trigger para totally patay yung ilaw.

OMNI yung brand, 100pesos lang. pwede na sigurong i reverse engineer yun. but surely, di yun isolated. simple, resistor - LED circuit lang yun.

yan namang circuit from tolits, magandang gawing digital out... para ON - OFF lang ang state...
