Hay guys need some help with my latest project. I wont go much into detail but my main question is can i use 2 RFID reader connected via I2c to An Uno simultaniously. The idea is that its almost like the Movie , in a submarine there need to have 2 officer turbin the key simultaniously to activate missile. I warna do that but only itu RFID card. Is it posible???
Currently Im looking at this product
www.lelong.com.my/nfc-rfid-pn532-i2c-module-arduino-project-ebazaar-I1360448C-2007-01-Sale-I.htm
However this product have very limited descrition as far as i can say that this product dont have selectable I2c id..
If this is not an option for my project can i make use of 2 AtTiny to be slave that fuction as a serial reader RFID interface and would transmite back to the Master as I2c?? Any help would be greatfull and hope you guys would/could suggest any other idea to make my project a reality.. Tuhanku in advance for any help you guys can give...
