Tell us about yourself!
would like to know this too. I have a feeling it isn't possible
Than you for this instructable. I was wondering if you (or anyone else) had any success with using this for colour detection in liquids? I'm trying to use it for water quality reagent identification, but my results are very fluctuating. Might just be my b/w samples that aren't good enough - just feel like I tweaked and tweaked forever without good results. I have an RGB LED in the tube on the picture, and the LDR next to it. Both in each their own tube, so no direct light from the LED hits the LDR.
