RGB VU METER - For Eurorack Synthesizer

The 2HP Eurorack VU Meter Module offers a compact and efficient way to monitor audio signals within your modular synthesizer setup. This module features a 10-pixel RGB LED strip that provides clear, real-time visual feedback of your signal levels. The LEDs shine through a transparent PCB panel, adding both functionality and a subtle aesthetic touch to your rack.
Key Features:
Real-time Signal Visualization: The module uses a 10-pixel RGB LED strip to accurately display the amplitude of audio signals in real-time.
Multiple Color Schemes: Select from 25 different color schemes to match your visual preferences and functional needs.
Three-color Audio Schemes with Clipping (5x): Different segments of the LEDs indicate safe levels, moderate levels, and clipping above 5V.
0-5V Voltage Schemes (5x): Cover the entire LED range to display voltage levels from 0-5V with smooth color transitions.
Colorful Audio Schemes without Clipping Indication (5x): Various smooth color transitions for aesthetic signal display without specific clipping indicators.
0-10V Voltage Schemes (5x): Each LED represents 1V, covering the range from 0-10V.
Single Color VU Schemes with Clipping LEDs (5x): Single color for safe levels and red for clipping above 5V.
Voltage Measurement Ranges:
Standard Range (0-5V): Suitable for regular voltage measurements.
Extended Range (0-10V): For higher voltage measurements with each LED representing 1V.
Audio Schemes: Include a clipping range for signals above 5V.
Inactivity Mode: The module enters a psychedelic mode with smooth color transitions when no signal changes are detected for a specified duration.
Dot Mode: Option to light up only one LED at a time, indicating the peak signal level.
Button Control: A single button allows for easy switching between color schemes and toggling of Dot Mode. Long-press to switch modes, short-press to cycle through color schemes.
Memory Retention: The last chosen color scheme is saved in EEPROM, ensuring the module starts with the preferred scheme after power cycles.

Idea for version 2, make the power chainable so you can connect 2 with one power cable.
