Shorted 5v to Ground on arduino UNO

Hello!

While I was testing a stepper motor code today with an arduino UNO R3, I accidentally shorted 5V to Ground. I smelt something burning and smoking, so I immediately removed the power from the board.

The board is still working. Do any of you guys know what burnt? Can I still use the board?

Thanks!

If you have a multimeter nearby you PROBABLY should test the output voltage of LDO regulator which means you need to measure the voltage of the 5v pin then maybe try to upload a simple sketch (if the voltage is ok) and see if it works or not
