Guru, correct me if im wrong here, but, if i had 3 LM3915, one for each color, and they all took the same audio signal and divided it up, wouldn't the lights always be white?
Just for example, wouldn't the 3915 put out the same exact amount of voltage for each color?
I was under the assumption that the 3915 only took an audio signal and divided it up into multiple outputs, each one less than the previous one. The MSGEQ7 takes the audio signal and splits up into frequency bands, then the arduino assigns each band a color, THEN im taking the signal and dividing it up into multiple outputs.
Is there a way i can send my blue, green, and red output digital signal from my arduino to the LM3915 and use the LM3915 to chop that signal up into different outputs, each one less powerful that the previous one? I was under the assumption that the LM3915 needed an audio signal input and wouldn't function with a signal from the arduino?
Perhaps im totally wrong here though.
