DO blinky pins

 1'''
 2DIO - DO_blinky_pins.py with synchronous mode.
 3
 4This example illustrates the process of writing a high or low signal to a DO pin from USBDAQF1TD.
 5
 6To begin with, it demonstrates the steps required to open the DO pin.
 7Next, in each loop, a different voltage output is applied, resulting in a blinking effect.
 8Lastly, it concludes by closing the DO pin.
