Hello guys,
I hope all of you are good.
please I need a help.
I am using an attiny 85 digispark.
How can i see the serial monitor for this device by using arduino program.
Many thanks.
Tanta,
Your question is not complete or clear and has a good chance of being ignored by the experts.
So I will give it a try.... 
The Digispark device IS a serial adapter. So you need to tell us how you intend to use this device.
By simply plugging into a USB port, the computer should recognize it and Windows will ask for a driver.
Once you install that driver, the device will be ready for action and it will show in the Device manager with a COM port associated with it.
If you select that COM port in the Arduino IDE software you will then be able to open the Serial Monitor and see the output on that COM port.
In order for that to work, the other end of the Digispark must be connected to a serial port on something compatible and that something needs to send out information to that port in order for you to see it in the Serial Monitor.
So if you plug it in and nothing shows up, it doesn't mean it's not working, it just means there may not be any data to display.
So post details on what you are trying to do and also how you have it connected to get a better answer.
Thank you dear.
I get the answer from you:
If you select that COM port in the Arduino IDE software you will then be able to open the Serial Monitor and see the output on that COM port.

You are wrong somedude !!!
Read that:
The PicoDuino does not have a hardware serial port nor a hardware serial to USB converter. An example library (DigiUSB) is provided, as well as some example code and a serial monitor like program, but communication with the computer will not always be plug and play, especially when other libraries are involved.
The PicoDuino supports all features found in the IDE with the exception of the serial monitor and the burn bootloader functionality.
What are you talking about?
Where in your post do you mention Picoduino?
I've been wrong before and, you are right, I was wrong to interfere this time as well.
