Help with installing MSGEQ7 for my IoT project

Projects General Guidance
1

I am trying to create an IoT broadcast lamp project, which has main features:

REAL-TIME MUSIC SYNCHRONIZATION

  • Creating lighting effects that harmonize with the music being played
    BROADCAST CONTENT ADAPTATION
  • This lamp connects to broadcast platforms via Internet connection USER PERSONALIZATION
  • Can set color preferences and lighting patterns
    AESTHETIC DESIGN
  • This Broadcast Lamp is not just a technology device but also a decorative element that beautifies the space

I am encountering issues with installing the MSGEQ7. I have already used GPT and Grok and searched for sources on the internet, but they all provide different results. I want to try everything but I'm afraid of damaging the MSGEQ7. Is there anyone here who can help?

Hi
Using a MSGEQ7 is a quite easy, the datasheet has a detail explanation of the protocol.
The main issue are the chips itself. There are many fake or damaged MSGEQ7 on the Ali and Amazon.

As an example of using a MSGEQ7 see this:

Try to NOT use AI, it's not reliable and will not teach you. Books are for learning, YT for eye candy, AI for nothing.
Your project is very doable for a new person.

I don't know where IOT fits-in but note that the MSGEQ7 requires an analog signal.

P.S.
I've made several sound activated lighting effects but nothing with the MSGEQ7 or any frequency analysis.

But just to get you off-the-ground, take a look at my World's Simplest Lighting Effect.. It also takes an analog input which can be a line-level or headphone-level signal, or you can use a "sound sensor" microphone board.

are this correct? :

  • Pin 1 (VDD) - connect to 5V
  • Pin 2 (VSS) - connect to GND
  • Pin 3 (OUT) - connect to Arduino analog pin (for example A0) and add a 200k resistor to GND
  • Pin 4 (STROBE) - connect to Arduino digital pin (for example pin 4)
  • Pin 5 (IN) - connect to 100k resistor, then to 100nF capacitor, then to audio source
  • Pin 6 (GND) - connect to GND
  • Pin 7 (RESET) - connect to Arduino digital pin (for example pin 5)
  • Pin 8 (CKIN) - connect to 200k resistor then to VDD, and add a 33pF capacitor to GND

No idea, never heardof the MSGEQ7 before, but it looks like good info at post #3. Also note comments in post #2.
