Led display propeller
The document presents information on a propeller LED display. The display uses a phenomenon called persistence of vision, where images displayed at 25 images per second appear continuous to the eye. It consists of a microcontroller, LED module, DC motor, and interrupter module powered by a DC supply. The rotating propeller display is able to show messages, numbers for clocks, and has advantages like low power consumption and self-cooling. Its applications include displaying messages and numbers in a novel rotating manner.
