ABSTRACT
Each year there are changes in public transport, to make life easier for many people
with disabilities to have access to the bus, but there is no system, the charts, to facilitate the
visually impaired to know what public transportation is circulating through the time .Thus,
some lose their transport and often depend on the goodwill of others to follow the correct
route. Conclusion The present work is the development and elaboration of a prototype system
for identifying the bus route, with its use in parades, to facilitate future passenger and the
driver. Work is divided into a control step on the numeric keypad and an LED panel system
using the voice chip ISD2590, implemented in a PIC16F877 microcontroller from Microchip
®. Will present the control circuits, the systematic functioning and timing system. You will
then be exposed to C language development of the audio system. In the end, the prototype
will be validated and performed an analysis of future innovations and because of its use today.
Keywords: Microcontroller, ISD2590, LED Panel, Keypad.
