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)
Today I assumed that the attiny 13 is correctly built in when the small point is where the half circle is in the diagrams. In other words VCC and RES is next to the point. I tested it the other way today and smoke came up. Classical smoke test.
Now let's get to the ATTiny13 included in the package. Mine has on its back a print L8 Taiwan R1 and on the left top BF3.
