the lights on the arduino are all glowing i.e. the L,TX,RX and on
when i connect it to my pc or 12 v power supply, all the lights come on. It is not recognised by the arduino software
i tried uploading a blank sketch, changed the serial ports, plugged it in other sockets, other computers, all to no avai. I know nothing is wrong with the board as i have used it before and it was working just an hour before this issue.
normally it would look like this
