Very basic arduino password cracker.
The leonardo try the 10000 password from the SD card line after line.
The method is based on my other projects (rfid windows login), the challenge here, is to read the password.
Unfortunately after arduino found the right password, the arduino keep trying.
The connection as the sd example.
After the arduino connected to the pc, waiting 5 sec before start the typeing. Its a safety solution when need to change the code, the program not write into the new program.
(But can add a button to start the program)
