hey, i ve been working on the photodetection property of LDR.
i need to know which one of the 3 photodetectors s better for the detection of red light. right now i'm using an LDR. i need to convert the output to frequency. how do i do it?? or is it better tht i use a phototransistor and use v-f converter.
