In this tutorial, a project on creating a wireless RFID reader will be implemented. The model of RFID reader used here is RFID reader 232N (RFID-IDR-232N) which actually can be connected to PC directly through RS232 using the DB9 (Male) of its cable for sending tag’s IDs scanned to computer.Somehow, the establishment of a wireless RFID reader enable the RFID reader to be place a t a further distance from the PC since the cable length constraint is eliminated but still can sends the tag’s IDs scanned to PC through the wireless link.
To deal with computer keyboard, we have to know what kind of signal did keyboard giving when you press a key. For this project, we are going to interface the Arduino Duemilanove to computer through USB.
Universal Asynchronous Receive/Transmit (UART) has becoming a popular item on sending and receiving data in the fast way. In here, we are going to experience on how to use UC00A to communicate with our computer/PC and SK40C.
