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!

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.
