4. What is Arduino ®
Arduino ® is an open-source prototyping platform based in easy-to-use hardware and software. Arduino ® boards
are able to read inputs – light-on sensor, a finger on a button or a Twitter message – and turn it into an
output – activating of a motor, turning on an LED, publishing something online. You can tell your board what to
do by sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino
programming language (based on Wiring) and the Arduino
® software IDE (based on Processing).

www.arduino.cc and www.arduino.org for more information.

6. Use
1. Connect your controller board (VMA100, VMA101…) to your computer using a USB cable.
2. Start the Arduino ® IDE and load the “VMA405_MFRC522_test” sketch from the VMA405 product page on
www.velleman.eu .
3. In your Arduino ® IDE, select Sketch

Include Library

Add .zip Library.
4. Now, select the RFID.zip file from the directory where you previously stored it. The RFID library will be
added to your local library.
If the Arduino
® IDE gives you a message that the RFID already exists, then go to
C:\Users\You\Documents\Arduino\libraries and delete the RFID folder. Now, try and load the new RFID
library.
5. Compile and load the “VMA405_MFRC522_test” sketch into your board. Switch off your controller board.
6. Connect the VMA405 to your controller board as pictured below.
