You'll synchronize a BLDC motor's RPM with precisely timed pixel data on a WS2812B strip, using Hall effect feedback and an Arduino Mega 2560. The result is a programmable, mid-air canvas that can show animations, text, or even your own logo, making it a showstopping engineering project for hackathons, exhibitions, or your final-year demo.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou will assemble and program a rotating LED fan that generates stable, high-resolution POV images visible from all angles.
