Would you cair to defend that remark? Last time I looked the laws of physics were the same if you are doing a hobby or not.
If you put different colors in parallel, only the lowest voltage LED will turn on. And hog all the current.
LED brightness never changed.
In its basic form (Weber law), this implies that eye response to object luminance, as brightness discrimination, is not proportional to its actual (physical) intensity level; rather, that it changes with the intensity level, remaining nearly constant relative to it. This, in turn, under assumption that the relative value of just noticeable difference in brightness sensation is a unit of the sensation change, means that the perceived object brightness changes with the logarithm of object's actual brightness.
My hobbies are to please only me.
People should stop blindly copying old circuits and look around at what's available today.
This comment sort of bugged me as I would beg to differ.
since I only have a few 1k resistors.
Nevermind that 1 k is the wrong value. We can address that when he learns to wire his circuit correctly.
Is it wrong?
