My uno is connected but i am not getting any port option in arduino ide. Also in device manager there is no port for the arduino .Previously I could upload and everything was fine.
Help pls
P.S.: I am on windows 10
What has changed ?
-
different board ?
-
different USB lead ?
-
genuine UNO ?
-
change/update to Windows?
-
does board work on another PC?
Anything connected? Try without anything connected.
What was previously connected? If you wete not careful, stuff using a higher Vcc might have damaged the board.

I've deleted/merged your other cross-post thread hijack @Kostubh4312.
Cross-posting is against the rules of the forum. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend 15 minutes (or more) writing a detailed answer on this topic, without knowing that someone else already did the same in the other topic.
Repeated cross-posting or thread hijacking will result in a suspension from the forum.
In the future, please take some time to pick the forum board that best suits the topic of your question and then only post once to that forum board. This is basic forum etiquette, as explained in the sticky "How to use this forum - please read." post you will find at the top of every forum board. It contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
I was trying to make a obstacle avoiding car with the L293D motor driver.
No changes to anything whatsoever.
Well i did use a led driver to power it temporarily and the led driver stopped working suddenly.
That is all !!
