So 56 of them
And the microphone I have is silver, has a black top and has two regular pins and one flat pin on the bottom.
I may need help with coding
QuoteSo 56 of them56 RGB LEDs will need 168 PWM pins. Which Arduino do you have that has that many PWM pins?QuoteAnd the microphone I have is silver, has a black top and has two regular pins and one flat pin on the bottom.Good thing it isn't the orange one.QuoteI may need help with codingProbably.
and what about the microphone being orange.. was that just sarcasm?
Quoteand what about the microphone being orange.. was that just sarcasm?Color and number, style, and location of pins has no bearing on the suitability of the microphone. So, yes, the color comment was sarcasm.What is it that you want to display with the LEDs? Volume? Frequency? Some sub-set of frequencies?There have been plenty of posts about controlling large numbers of LEDs. There is even a search box up there. Do some research. The hardest part is powering all the LEDs. The second hardest part is being able to PWM a large number of LEDs while still maintaining adequate refresh rates and on-time for visibility.Getting audio data from a microphone is not that difficult, but it might require amplification and offset. It all depends on the microphone. And, no the color is not important.Separating the audio information by frequency is not a trivial task. There are chips available, cheap, that do it in hardware. Getting one of them simplifies the job considerably.
