For a class project I'm trying to create a light controlled lamp, but I was hoping to check with everyone here to see if it would work (I found the diagram online) and also where I could position the photocell so it is not effected by the light it is powering. Thanks.
If you're trying to control the brightness of the lamp by adjusting the light on the sensor, than you don't want a relay. The relay is either on or it's off. There is no in-between. In order to control the brightness of the lamp, you'll need to have varying voltage/current. You can't really do that with a relay.
How would I alter the circuit diagram then to make this more plausible? Thanks for the response!
Well I don't really have enough information. What kind of lamp are you using?
You might be able to simply replace the relay with the lamp, but like I said, it depends.
Just about any small 12 volt lamp should be okay. It also depends on what battery you're using. An automotive light bulb might work. Just a small one, like from a dome light. Don't try a headlight
So I would be able to replace the relay with an automotive light, and that should (in hopes) work?
Well, from what you tell me, what I'm trying to create is a indirect light relationship. I want to be able to control a lamp with this circuit, having it turn on (or get brighter, I don't mind which one) the darker it is in the room, and turn off (or dim) when it gets brighter in the room. As far as more information, unfortunately I have a very base knowledge of how circuitry works. I'm attempting to put this circuit together in Yenka to see if I can get it to work, but mostly everything I'm trying is trial and error, most likely a result of my extent of knowledge on the matter. I hope this makes sense, and sorry I can't provide much information.What exactly are you using this circuit for? Any more information about what you're trying to do would be greatly appreciated at this point.
