MSGEQ7 bad or is the circuit bad?

Using Arduino Audio

I'm currently trying to finish a project, and I have a large obstacle which is that either my circuit is bad or my four MSGEQ7 chips are bad. I have the same setup as this guy. My serial monitor on the Arduino code is coming up like this.

Here is some photos of my circuit.

Did you buy them from a reputable supplier? It seems there are lots of fakes/rejects floating around.

That might be fine depending on what kind of signal you're feeding-in. :wink:

Yeah! I bought them on sparkfun so it's decently reliable.

Its quite hard to see...

is the powerrail in the middle of your breadboard connected to something?

No there isn't

I trust SparkFun...

I'm not going to try to figure-out you're wiring from the photo...

If you have a multimeter you can confirm the connections. It might be something as simple as miswiring the audio jack.

And, you didn't say what kind of audio signal you're feeding-in. Are you running test-tones or regular program material? And, I believe it needs a relatively "loud" line-level or headphone-level signal. It won't' work with an unamplified microphone signal.

...If it was me, I would have bought this or this.

Maybe you can try with power and ground...
