Real-Time Ambient Lighting using WS2812B LEDs and Arduino Nano
Control your PC lighting dynamically and extend on-screen visuals into your room with this immersive RGB setup 🌈
This project uses an Arduino Nano + WS2812B LED strip with an improved Adalight protocol for smooth, real-time color syncing.
What you need:
• Arduino Nano
• WS2812B LED Strip
• Breadboard
• JST SM 3 Pin Connector (Male)
• Connecting Wires
How it works:
Your PC captures screen colors and sends RGB data via serial communication.
The Arduino:
• Detects “Ada” header (Adalight protocol)
• Validates data using checksum
• Updates LEDs instantly
Result → ⚡ Smooth, flicker-free, real-time lighting synced with your screen
Why this setup is powerful?
• Ultra-low latency response
• Stable output with checksum validation
• Smooth transitions during fast scenes
• Perfect for immersive setups
Applications:
• Gaming setups 🎮
• Movie & streaming ambience 🎬
• Smart desk aesthetics 💡
• DIY PC customization
