DO blinky port

 1'''
 2DIO - DO_blinky_port.py with asynchronous mode.
 3
 4This example illustrates the process of writing a high or low signal to a DO port from USBDAQF1DSNK.
 5
 6To begin with, it demonstrates the steps required to open the DO port.
 7Next, in each loop, a different voltage output is applied, resulting in a blinking effect.
 8Lastly, it concludes by closing the DO port.
