I bought the spx-14258 sensor and I have doubts in programming, I wanted it to identify only the green color. For example, every time the sensor identifies the green, LED it would turn on.


Thank you for your help!!

If you had checked out the datasheet on the device, you would have seen that it contains 6 sensors, none of which respond to the green wavelength (495-570nm). The spx-14258 device goes from ~570 - 890, give or take.
So, I think you're going to be disappointed.

But what if I wanted to detect red instead of seeing what the programming would be like ??
