Abstract
Conventional methods of displaying images to public are using LCD display and dot-matrix LED board. Propeller LED display is a device that project an image or time as if the images are floating in the air. The floating image is received because of human eye limitation. Actually the floating images emerge by synchronizing LED's blink to form an image at particular time and rate. The programming of PIC is using Assembly Language. This project consist two main circuit; motor controller circuit and LED circuit. 9VDC will be used to supply the power for motor controller circuit. Then the motor controller circuit will provides power to LED circuit and DC motor. When DC motor is rotating, the floating image will appear. The synchronization of DC motor speed and LED blink cause the image visible to human eyes. So the desired image such as clock, date or symbol can be programmed and displayed.
