Care to try that sentence in English? I recognise the words but can't make them convey any meaning.
What I meant was, that when there is no light reaching the photoresistor, the value that it has is 900 approximately, and when i bend my finger a little bit, the value that I get from the photoresistor is 800 and the last value is 260 when the led is so close to the photoresistor(all in the serial monitor of Arduino)
