Hey guys,

I haven't tried this out and that's why I'm writing here, can photoresistors detect infrared light? can they vary their resistance depending on how much incident light they receive from the LED?

 

Hello,

This page has a lot of information on LDR's:

Infra Red has much longer wavelenghts.
See the attached PDF for more info.

Photoresistors come in many different types ,their spectral region of the light differs so it depends on which type of photoresistor you are using.

Good Luck

 

Thanks a lot, it helped!
