| Jun 1, 2015 at 16:07 | comment | added | cocco | also the leds' have not the best info ... for example what is the best voltage for every color??? it says only 2.1 to 3.2. so it's also hard to decide for the proper resistor... normally r = 2.1 g= 3.1 b= 3.2 | |
| Jun 1, 2015 at 16:02 | comment | added | cocco | on the leds i only need the nm ... right? not the mcd.At the other side the LDR has not much info in the datasheet | |
| Jun 1, 2015 at 16:00 | comment | added | cocco | yes exactly that!! i don't know how to apply that values. | |
| Jun 1, 2015 at 15:59 | comment | added | geometrikal | Can you make your question more concise? By the way, have you looked at the datasheet for the LED and LDR. The LED datasheet will have the wavelength of each R, G and B component and the LDR datasheet will have its spectral response. | |
