I leave a new tutorial I did recently with my Arduino Yun and a reader RFID ID-20 for make a access control, I must admit that cost me quite put together the code (in fact, i asked several things in the forum) but if they find something, any errors or suggestions, are free to modify it.
The projector is creating to do a RFID access control with a MySQL database hosted a tables for the users and other for make a control that the cards read. This interface will do it with PHP and Python to communicate with the database.
I hope it will be helpful!
Greetings to all!
