Propeller Clock Display
Journal Title: International Scientific Research Organization Journal - Year 2015, Vol 1, Issue 1
Abstract
Conventional methods of displaying some data to public are using LCD display and dotmatrix LED board. Propeller LED display is a kind of thing that project an image or time as if the images are floating in the air. The floating image is received because of slow response of human eye. Actually the floating images emerge by synchronizing LED'S blink to form an image at particular time and rate. The programming of microcontroller is using Assembly Language. This project consist two main circuit; motor controller circuit and LED circuit. 5Vdc will be used to supply the power for motor controller circuit. LED circuit consist of polymer battery will provide power to LED circuit. When AC motor is being rotated, the floating image will appear. The synchronization of AC motor speed and LED blink cause the image visible to human eyes. So the desired image such as real time clock, date or symbol can be programmed and displayed.
