Arduino UNO audio input from 3.5mm jack

Projects General Guidance

I am fairly new to Arduino and I can't seem to find a good answer on the Internet, so I have decided to use the forum. Basically, I want to build a sound reactive led strip with a 3.5mm jack input. The hardest part for me is the sound input. What jack should I use, how to connect it to my Arduino and would I be able to control well my led strip with the values that the jack gives?

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.

How do you want the strip to react, just change colour and brightness or do colour patterns.

Here is a great tutorial from Sparkfun using addressable LEDs.

This might help too;

I googled arduino sound modulation leds

Hope it helps.. Tom.. :slight_smile:

Maybe look at something like this: Microphone Sensor AVR PIC High Sensitivity Sound Detection Module For Arduino | eBay.

To connect to a standard Uno, use duPont male to Female connectors:

Thank you for the fast answers! Is there a way to skip the microphone module and input directly from a jack?

Edit: Found a good step by step tutorial on how to input audio:
