14. FUTURE DEVELOPEMENT
• Can Enhance its Real Time Operation because
of the Application PCB Flexibility
• Can be Interfaced with Computer for Serial
Communication ( using VB 6.0 )
• PC can be source to an Ocean of messages using
multistage Response

16. CONCLUSIONSCONCLUSIONS
• Excellent & Efficient way to satisfy small concern
• Very simple, as explained in modular format
• Gives clear understanding of various areas of technology involved
in compact & crisp manner
• Errors can be easily detected & only defective component of the
unit needs to be replaced
• Especially important to start – ups since the cost involved is less
• Wide application in schools & colleges
example :-
results of examinations can be stored and the candidates can
access it via their telephone rather than come all the way to their
institution !
