Abstract
This project comes up with possible means of attracting the attention of the public to be able to see the time table even at night. The timetable is designed and constructed in such a way that the Light Emitting Diode (LEDs) were arranged to display the timetable and the alarm to draw the attention of the students. The design basically utilized rectifiers, pulse generator, NE 555 timer and Decade counter (i.e. CD4017) transistors which act as switches to the Light Emitting Diode (LEDs).
