TOUCH SCREEN BASED WIRELESS SCHEDULE TO COMMUNICATE WITHIN AN ORGANIZATION.

Abstract

Touch screen is evolving at such a rapid pace that new doors have been opened in this field of
application and also in wireless communication application using touch screen. This project is a combination of
both touch screen and wireless application using radio frequency as a mediator. The main purpose of the project
“touch screen based wireless schedule” is to develop healthy wireless communication with in an organization
(Here organization refers to multistoried shopping mall) without the need of personal interaction.
With the touch of the finger tip on the touch screen attached to daily scheduling, the co-ordinates are scanned
and the value is sent as input to encoder which is driven by driver to PSOC kit and displayed on LCD screen for
customer’s need, which is then sent to receiver’s end with the use of RF sender.
RF receiver is tuned properly to receive signal at server end. The distance between them up to 5m-6m. With the
help of monojack, the values or signal transferred from sender side are copied into DTMF decoder and the
decoded value will be sent to PIC microcontroller, which reads the received data and send it to PC with the use
of MAX 232. The values will be converted by MAX 232 from TTL logic to RS 232 logic which is then sent to
CPU using RS232 wire .
This project not only helps in making individual work easy but also makes the work productive
