Ok, I did my first steps to control an electro motor with arduino, today I bought myself a "learning package USB" from Franzis.
I plug it into my computer's USB port and it appears as /dev/ttyUSB0. I can then use it to switch on and switch off an LED.
Python program to play the note A (440 Hz):
import serial, time
conn = serial.Serial('/dev/ttyUSB0',
baudrate=9600,
bytesize=serial.EIGHTBITS,
parity=serial.PARITY_NONE,
stopbits=serial.STOPBITS_ONE,
timeout=1,
xonxoff=0,
rtscts=0)
while True:
conn.setDTR(True)
time.sleep(1/880)
conn.setDTR(False)
time.sleep(1/880)
