Hi,

is there any way to detect LED color light using Arduino?
it is not detect static color, but LED color light.

Thanks.

An LED is also a color-selective photodiode, but is most sensitive to light about 50 nanometers bluer than its own emission maximum wavelength.

Or use a color sensor module.

Hi Jremington,

I can get color sensor module here, I'll try using Color Sensor Module first

Thanks.

Use three photo transistors each one with a coloured filter over it for red green and blue. Colour sensor modules tend to have red green and blue LEDs and work off reflected light.

Alternatively use. https://howtomechatronics.com/tutorials/arduino/arduino-color-sensing-tutorial-tcs230-tcs3200-color-sensor/

Hi Grumpy_Mike,

I will try to use as in link, it's a module that i can just use it.

Thanks
