I am using LDR sensor in my project. The source of light comes from the different colour of images. As we know, the spectrum of each colour is different and it will produce a different intensity of light. I know, the colour sensor able to do this task but it's not listed as options.
Here I attached the schematics and LDR datasheet as the reference (http://kennarar.vma.is/thor/v2011/vgr402/ldr.pdf)
My question is how to increase the sensitivity of this sensor so that it is able to measure the change of resistance within 200ms?
