First sorry for my bad english, not my native lenguage.
Today I started working on my Arduino nano (first time used). When plugged for the first time the "L" led started blinking, after that I tried to write a simple program but I noticed that the "Port" option on the Arduino IDE was Gray. So I couldn't choose the port. After that I searched A LOT but nothing seems to work.
While trying to test if the problem was the Arduino and not the PC, I make a simple circuit with 1 LED, 1 resistor of 1Kohm, and a breadboard. I connected the 5V pin to the LED and GNG to the other point, And when I did this the "L" LED stopped blinking forever. I am 100% sure that I did not make a short circuit. ¿Maybe the breadboard is in a bad state?
-The port doesn't appear at Device manager (tried every port of my notebook).
-The "POW" led is ON when I plug the USB.
- The Arduino is a clone (chip CH340G).
So now I don't know if the problem is the port or if the Arduino Nano is dead because of a possible short circuit between 5V and GND pins.
thanks in advance!
