Discipline: Programmable Running Message
The study aimed to create a device which could display messages of five choices stored in the memory. A speed control was also available which could allow the user to view the messages in a low, moderate, and high speed. The device could display messages in a low, moderate, and high speed performance and the messages could either blink or display one by one.
Experimental development and descriptive approaches were the methods used to test the functionality and practicality of the design.
Findings showed that the device was very convenient and useful in highway billboards. Furthermore, since the billboard was computer program controlled, the user could easily change the mode and select a message to display.
