I'm using the FastLed lib for the ws2812b strip so I soldered a USB connection to the 5V and GND for getting power from a powerbank.
and I'm using bluetooth HC-06.
once I tried to upload my new sketch unsuccessfully.
When I'm uploading the same sketch to another nano everything is ok.
maybe it was overheated or even fried?
p.s sorry if I said or did something wrong. thanks for helping!
I copied the error:
