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).

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.

WARNING
The VCC of your VMA405 must be connected to 3.3 V on your controller board.
Do not connect to 5 V as your VMA405 will be destroyed!
7. The example drawing shows an LED. You can also use a buzzer (VMA319), a relay module (VMA400 or
VMA406)… In the example drawing, only pin 8 controls the LED. Pin 7 can be used to control a relay when a
valid card is applied.
8. Check all connections and switch on your controller. Your VMA405 can now be tested.
9. In your Arduino®IDE, start the serial monitor (Ctrl + Shift + M).
10. Bring the card or tag in front of the VMA405. The card code will appear on the serial monitor, together with
a “Not Allowed” message.
11. Copy this code, check line 31 in the sketch and replace this card code by the one you copied.
* This integer should be the code of your card/tag.
*/
int cards [][5] = {{117,222,140,171,140}};
12. Recompile the sketch and load it into your controller. Now, your card will be recognized.
