The RFID reader turned on an LED?

but i wana know if theres a way for me to emulate keystrokes

wana? Get off the lazy streak right now.

If you have two hands, why do you need to emulate keystrokes? Just push the keys.

Or, are you referring to having the Arduino emulate keystrokes. Certainly the Arduino can act as though any switches attached to it have been pressed, whether they really were, or not.

after it receives a command over the serial line.

“It”? What is it? The RFID reader? How is it connected to the serial port?

can som1 plz help me?
