I am working on Arduino UNO using the AdaFruit pn532 NFC / RFID shield. The goal is to have a shoe box with a false bottom. Under this false bottom will be my prototype, which hopes to recognize every mifare tag (up to 6), which is in the box, above the false bottom.
I started with one shield and found up to two tags in a range.
If I put one tag, it registered again and again one tag in the loop () of my sketch.
If I placed two tags above the screen, he registered two tags in an alternating pattern. ("Tag1", "tag2", "tag1" ....)
But when I posted three tags, it only writes the third tag. This essentially uses the adaFruit mifare example.
Then I installed UNO with two screens, and in the loop () I checked that both of them worked in exactly the same way. As soon as there were three tags, no matter on which pn352 they were placed (2 on one, 1 on the other or all three on one), it registers only one tag.
Has anyone tried to create something that detects up to 6 tags? If you could share your discoveries?
New for Arduino ..
