Audio Reactive LED Turntable

Audio Reactive LED Turntable


Developed by Michelle Brown, January 2022.

The idea is to create an audio reactive LED lighting option for a turntable using micro-controllers.

For Xmas 2021, we got a Pro-Ject turntable with a lovely translucent glass platter. This gave me the idea of adding an RGB lighting system under the plate to create something pretty and fun for the lounge room.

After looking online at what some other people had being doing for this idea, it seems pretty straightforward to get some fun RGBs happening, but I also thought, let's make this a bit trickier! So I have added the idea of making the LEDs audio reactive to push the creative brain muscles some more.

First thing to decide on is materials, I've been watching a few tutorials online to see how others have approached this so sharing these links below.

Turntable LED options

Keep in mind that most of these videos are of similar model turntables to mine, but as long as you have a record player that has a removable plate and space underneath, you could add some lighting.

I liked this one for simplicity and neatness -

There are several DIY 'neatness' options if I wanted to choose strip lighting instead of a circular LED system, I'd probably 3D print something though if I went down this path -

There are a couple of options that could be used for the neat circular LEDs;

  1. Like the first video above is an RGB LED Angel Eyes Halo Ring (131mm), made for car headlights mainly, a plug-n-play solution if we didn't want to add our own programming.
  2. Adafruit has NeoPixel ring lights that are programmable, but keep in mind you purchase as quarter pieces

For this project prototyping I am going to testing with both strip LEDs and the NeoPixel option.
