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.
Ever think to create a wireless servo controller to control movement of servo motor at a distance? If yes, this tutorial is totally applicable to you. In this tutorial, a wireless servo controller circuit will be established and a servo motor will be controlled wirelessly from a computer through a Servo Control Panel GUI provided by Cytron Technologies.
Bluetooth wireless communication is becoming more and more common recently. In response to this trend, Cytron Technologies has came up with a new Bluetooth module called BlueBee, which provides hobbyists a wireless remote control on their microcontroller circuits thus robots through serial port communication service attached with BlueBee. In the section, a simple project will be constructed to illustrate how to use BlueBee for wireless communication to interface another Cytron product, breadboard friendly Arduino, BBFuino to control LEDs.
The XBee and XBee Pro have UART interface and can be connected directly from microcontroller to pins of RF Module (XBee/XBee Pro). Using UART interface, we can use this wireless devices to communicate between microcontroller to microcontroller (two PICs) or between PC to microcontroller. Here, we will discuss how to use two XBee/XBee Pros to interface with microcontroller and how to send command for configuration XBee/XBee Pro Module.
