Parallel port dongle (12C508A) By using the PIC 12C508 MCU from Microchip, we can make a cheap and simple hardware protection key (dongle).
Smart lock (12C508A). The base sends a data sequency (the password) which is recognized by the key. The key checks the sequency and -if it recognises it -sends to the base another data sequency, as an answer to the password. At the time when the base gets a correct answer (which means that the key has been introduced), the relay is put into action, and it can command a number of consummers.
