The ps2 controller is found but these symbols appear in the serial yy yy yy yy yy yy etc.
I changed the baud rate but is the same.
Can someone help me please
Baud rate must be the same. So if you have set in program serial baud rate 57600, then you must have 57600 in serial monitor. Because i have the same problem. Because default arduino speed is 9600 baud.
