    Using a circuit with a photoresistor

    Time flies when you are having fun...my slip it has been a couple of years since I first posted. I like the plain glass comment NascentOxygen...the amber pill bottle is plastic and may not be the best choice. Great forum by the way and thanks for the great input! Just a retired...

    Using a circuit with a photoresistor

    Hello Carlos and the other Wizards...it has been about a year since I have thought about this issue. First of all as suggested I made some changes...unfortunately more than one. What I did was add a .1 mic cap across the power feed to my circuit. Then I placed a amber pill bottle case over...

    Using a circuit with a photoresistor

    Hey thanks for the responses, The photoresistor is in series with 100k ohm resistor across 12vdc and off the center if this is a resistor 4.7k ohm driving the first of three transistors. the photoresistor is rated at 80mw and series VT is 900 whatever that is. Also rated from -40C to...

    Using a circuit with a photoresistor

    Hello Wizards, I am using a circuit with a photoresistor that sits under the eave and senses ambient light to turn on a light at night to shine on an American Flag. This works fine for a month or two and then quits working. What I find is the photoresistor goes bad. Ambient light in the...
