hi, i hope that this is the right place for this..
im want to built a puzzle, with four or more pieces identified by RFID or something like that.
the goal is to put each piece on a specific pedestal.
only if all the objects are on the right pedestal there would be a magnetic lock on a box opening..
id be glad for some guidance of al sorts...
whats the best way to build it, and program such a thing...
thanks everyone..
The readers should offer bus connection (I2C/SPI), not only serial.
