Reading RFID tags with C# and RDM630

 

Low Cost RFID

The RDM630 Proximity Reader Module is a low cost 125 kHz RFID  Proximity reader. It uses uEM 4100 or compatible card with  64 bit Manchester encoding and outputs the data to its serial port at 9600 baud. With this, RFID tags can be easily read by C# using the serialport module and can be integrated to larger systems such as inventory or attendance systems .

The output format of the reader is given as :

 

format

To create the simple interface, create a new project and add two labels, change text to COM Port and ID TAG respectively, add a combo box to contain installed serial ports, a rich text box to contain the data coming from the tags, a button which will serve as connect and disconnect button and add a serialport.

After adding the controls, lets make the magic happen! Add the System.IO.Ports namespace, we need it later to get all the installed serial ports on the PC and populate our combo box for the Serial Port Selection.

IO Namespace

 

Instantiate a new delegate for the received serial port event and initialize the delegate to use getRFID routine to capture the data from the reader.

delegate

At startup, we get all stored serial ports and populate the combo box for the selection of the desired COM Port

getSerial

For the Connect button to Open or Close the connection add the following
Button

To read the RFID data, we read till the ETX of the reader and display it to the richtextbox

get

Finally we test if it works

PBOT Graphical Programming with miniBloq

Pbot_Bloq

 

The PBOT is an entry level robotics platform that features 3 IR Collision Sensors, 3 Line Sensors and a 2 channel Motor driver. It is Compatible with all Gizduino Boards (An arduino derivative board) and all arduino form factor boards. It is a good starting point for beginners in the field of robotics. Line Follower, Sumo and Obstacle avoidance robot are some examples that can be done with this platform. To get things done, one needs a lot of programming to do what you like the robot would do. Using a Gizduino 328 board, it can be programmed using the Arduino IDE with the native C/C++ syntax. If you are a total beginner and do not have any background in programming but would love to learn can be troublesome. But there is still hope! It can be programmed with a graphical programming IDE  using Ardublock or Scratch for Android. Both IDE adds pure graphical programming to Arduino and Arduino compatible boards.

But wait! theres more! miniBloq is another graphical programming IDE that also generates the equivalent C code of the blocks good for learning the native language. Another good thing about miniBloq is its powerful XML backend that we could define custom hardware which means custom pin names for a specific hardware can be defined.

To get you started hardware file of the Pbot for the miniBloq is provided below. Extract the contents of the archive to miniBloq.v0.8x\hard and fire up miniBloq and start programming!
