Design and Implementation of Micro Controller Propeller Displays

Authors : Mohammed S. Saleh, Hanan Badeea Ahmed, Adham Hadi Saleh and Omar A. Imran

Abstract: The propeller display is a special type of circular LED display. By using of some mechanical assembly help, hardware requirement, LED count and later the total cost is reduced to very economic price. Additionally, repairing and maintenance of the display is so, easy that any technician or engineer can maintain it. The overall implementation of the synchronizing can be done through software. Propeller display which designed in this project, made using the 40-pin 16f 877A series microcontroller, using space multiplexing concept. The propeller display is mechanically scanned and shows the characters digitally and the greatest idea of this display is its crystal clear display. It’s includes only eight bright LEDs which are show the display through rotation. To build this display, it’s need for a small 40 pin microcontroller, LEDs and a position encoder. Propeller display can display the messages which will require anenormous 525 LEDs. Minimization of hardware and cost is achieved here.
