Embedded system demonstration with the aid of moving electronics message is common in our society today. There is a better, cost effective and lower power consuming device which could be used to demonstrate embedded system. The aim of this thesis is to research on propeller display in order to achieve this.
Propeller display uses the principle of persistence of vision which explains why eye can retain image for a brief time interval. It is a device made with seven or eight light emitting diodes which are arranged on the rotating arm of an electric motor.
As the arm rotates, characters can be displayed in a circular form. In order to achieve the design goal, modeling tools such as block diagrams, flow chart and sequence diagram were used to formulate the concept and determine how the propeller display works and what components can be used to develop the device. Programmable integrated circuit and microcontroller were studied, using microC PRO platform and Keil platform respectively. A study of the two devices and platforms revealed the various methods that can be used to develop a propeller display. Microcontroller and Keil microvision platform will be the best way to develop a reliable propeller display. This is because a good number of embedded system students have been introduced to C language course in their studies and C language is reliable for embedded applications.
