In this project, you'll use the nOOds flexible LED filaments to make light-up visualizers to plug into your CV outputs. CV synths are like musical circuits: you can send waveforms with varying voltages around your setup to create desired bleeps and bloops. Sometimes making a patch can feel like plugging cables into a nebulous void though, especially if you inadvertently create cable spaghetti. As a result, it can be helpful to visualize the signals with LEDs.
The nOOds are soldered up to audio jacks on either end to create a "cable". However, It's important to note that the nOOds do not carry CV signals, they're purely decorative.
The nOOds' anode (positive) is connected to the audio jack's tip and the nOOds' cathode (negative) is connected to the other audio jack's ground. The positive end is plugged into a CV output and then ground can be grabbed from any open jack.
This setup assumes for a 5V maximum output from your CV synth. If you know that the CV voltage you're using is higher or lower, you'll want to adjust the inline resistor to a different value for best performance.
