Been using a "light dependant resistor" as a color sensor in a test fixture I've designed.. To determine if a Bi-Color LED is either Red or Green... Its been working great as the intensity between green and red was far enough apart that the LDR had no problems detecting the difference..
BUT of course now I have a new fixture to design and the LEDs use in this product have the same intensity between each color..
Would some sort of "filter" (red disc or green disc) applied over the LDR help? Any suggestions on that?
I'm not well versed in color filters and what really happens
Or anyone have a suggestion on a low cost "color" sensor that I might try?
Biggest mechanical issue is that there are multiple LEDs about 3/8" apart so I'm afraid I'd need optical tubes with it...
