The LED Wheel is an embedded systems project designed to spin a single row of blinking LEDs and achieve persistence of vision.
Capturing the output of the LED Wheel with a video camera proved very difficult. Consumer video camera's usually capture video at a fix frame rate ( eg. 29.97 NTSC ). The LED Wheel outputs an image at 7 to 10 frames per second. This frame rate is enough to achieve persistence of vision on static images, for humans. But for a video camera to properly capture would require frame rate synchronization with the LED Wheel.
The first video is of the wheel displaying the "HELLO WORLD !!" pattern.
