Hey guys,
I have read up, and i have found it is possible to use a normal LED(green) in reverse to detect light.
How can i wire up a circuit using simple items? OP amp, transistor etc. I have tried the circuits that are available, and they do not seem to work. Has anyone done this here? if so how
Thanks
