Hi,
I have finished coding and have tried to upload but it says" board not available" This is my first time using Arduino.
Plz Help
Are you using the ONLINE IDE "CREATE" or the regular IDE ?
If its the regular IDE I would suggest starting HERE first
Ignore that its for a leonardo as the pictures also allow you to see the procedure to select your board and COM port.
If your issue is more than that then you really need to include much more informations and I would suggest starting HERE first
If its the CREATE IDE then ensure that your board has nothing connected to pins 0 and 1 as this could block communications.
CREATE will select the correct COM port and board for REAL Arduinos but for clones you need to specify the port itself and the board type.
