Hey,
I was making a circuit and writing a simple code (I am new to coding so im learning) and when I put my arduino in my pc. my pc detects that my arduino is going in and out and in and out and never stops untill I dusconect the cable. Now when I connect it again, or only the PWR led stays on or PWR, RX and TX stay on and my pc doesn't detect a new input to my usb. I also can't upload my sketch, there is nothing to uplaod to.
Can someone help me? Thanks!
