I was making an Arduino project. It was a very safe project as I copied it from Arduino's official website. The project was about adjusting the speed of blinking the LED on 13 pin of the Arduino.
I connected the potentiometer correctly as shown in the circuit diagram. Firstly the project was working fine, but after some time smoke started to come out from one of this pins - A0 , GND and 5V. I removed the power cable quickly. There was no damage to the board.
My questions are -
- What is the reason behind this smoke?
- Can these pins be used further? (I really removed power cable quickly.)

Thanks in advance.
