There are a lot of tutorials and also guidance on the datasheet. However, even though I repeated the same procedures over and over again, there is a constant beep sound and LED is on when I connect an LED to analog output which has the output of the msgeq7 IC’s signal.
Even the LED is not connected to 3.5mm jacks at all. So, how come this constant beep sound comes from the speaker.
Any idea what about the probably problem or anyone come across such a problem.
