Light Intensity Monitoring System Issue


Why does the LDR always show 1.02 thousand if light is sensed and some value between 200-600 if no light is sensed?

And what does this mean : Some students have received an LDR with internal resistance which is different from the standard. Try using the following combinations in the given sequence

3.3v - LDR - a0 Pin - 10k - gnd
3.3v - LDR - a0 Pin - 330 - gnd.


Please ask this question in the same thread where the original question was posted. Also, tag the student who had posted above point so that they could answer you. To tag use @ followed by the username e.g. @chinmayat11

Do keep this mind for other posts as well. Do not create a new thread unless there is no mention of that topic.
