Photo resistor to turn a led on/off? Answered
Hi, can I use a Photo resistor to turn a led on/off?
I'm looking at other projects and I see people tearing apart motion detector kits.
Can I just link up a photo resistor, 3v button battery and a LED in a series?
I want this to be as small as possible so I can't use any of those arduino things.
I just need the LED to either turn off or on when something is near it, I just want a reaction.
