Light Bar Add-On – Flash Into Action
Bring color, motion, and excitement to your Stackr robot with the Light Bar Add-On. Inspired by the flashing lights of emergency and service vehicles, this 3D printed module uses a set of 5 NeoPixel LEDs mounted on a sleek light bar to create vivid, programmable lighting effects. Perfect for learning about LED control, color mixing, and animation — or simply giving your robot a striking new personality.
What You’ll Learn
🔩 Mechanics – Assemble and mount the light bar securely on your Stackr. Learn about placement, cable management, and design choices that enhance visibility and aesthetics.
⚡ Electronics – Connect and power a NeoPixel (WS2812) LED strip using your Arduino Nano ESP32. Understand how addressable LEDs work and how a single data line can control multiple lights independently.
💻 Software – Explore creative coding and visual effects:
- Learn how to program individual LED colors and brightness levels.
- Create flashing patterns, color transitions, and animated sequences similar to police or emergency lights.
- Integrate lighting with other robot behaviors — for example, flashing when moving, charging, or responding to commands.
