I'm not sure what you mean by that. I think I'm just going to relate a change in voltage to the intensity.

I've found a website that gives actual values for each wavelength of coloured light. I was also wondering if the filter could come supplied with a wavelength. So I think I'll use this to draw a graph of voltage against wavelength, as with my circuit, voltage should go down as the intensity is...

Megegg, I was thinking of doing a very similar setup, only I'm going to use a potential divider, and work out the voltage over the LDR. My idea is that V out should decrease, as the light is shone onto the LDR. Only problem is, I can't see how I can draw a graph as the filters won't give a...
