This is a prerelease for early testing. The app is Apple Development signed for Team ID
8N738727QB, but it is not notarized. On first launch, right-click the app and choose
Open, or allow it in System Settings → Privacy & Security.

Highlights

• Native macOS menu-bar controller for WS2812B strips connected through Arduino USB serial
• Solid color, brightness, editable presets, and six Arduino-rendered effects
• Native Liquid Glass on macOS 26+ with an adjustable Glass-to-Solid appearance control
• Fast, collapsible control sections and automatic panel sizing
• Resilient LEDCTRL,1 handshake across the reset caused by opening an Arduino serial port
• Local-only operation with no accounts, analytics, subscriptions, or network dependency
• Rebuilt documentation with app screenshots, color-coded wiring, architecture, firmware setup,
  power-safety guidance, and complete serial protocol details

Hardware defaults

• Arduino Uno or compatible 5 V AVR board
• 128 WS2812B pixels
• Data pin D6
• RGB color order
• 3,000 mA FastLED estimated power ceiling

Read the wiring and safety section in the README before powering a strip. Do not power a full
strip from the Arduino 5 V pin.
