added a little bit of information...

| May 3, 2019 at 17:15 | comment | added | SoraCode | As for the RGB values, I needed it for the computation of vector values at different concentration perentages | |
| May 3, 2019 at 16:52 | comment | added | Majenko | Also, what do you hope to achieve doing this? The results will be, from a spectrophotometric point of view, meaningless. You are only testing 3 wavelengths within a whole spectrum of colour. | |

| May 3, 2019 at 16:47 | comment | added | chrisl | You gave us nearly no information. Please show your circuit and your code. And what does "not getting any good results" mean? Explain what you expected and what you actually see. | |
