Talking RFID access control

This is the combination of 2 projects. The RFID access control project and the Text to speech converter project. Both these projects can be done independently and then can be combined together to form this project. The RFID module will detect the RFID cards and will pull up information about the card from a database and provides access or denies it.

Usually LEDs or buzzers are used to indicate the status of the access request. In this project instead of LEDs or buzzers we will use a text to speech converter to produce real human voices. When John, who has access shows his RFID card, the system will check the DB and then greet him with a voice message, “Hello John, welcome to the office”. This is achieved by the main controller of the project sending text information to the text to speech converter. Most of the converters have serial input.
