Flickering Problem

Hi, i ve recently bought an Arduino Uno and after pluging it into my pc i noticed it started flickering. My question is: is it alright? It s worth mentioning that the light is labeled with a L and is red

Hi @andreienescu ,
Generally speaking, new arduino come with the blink sketch loaded into it.
This sketch makes the red LED blink every second.
If it's flashing every second it's normal.
