Hey, I was wondering if anyone could help me on a problem I've been having: I've recently joined an engineering class that uses arduino megas (2560's) for various sorts of projects. I've picked up one of the megas from my teacher and I've been trying to get it to work for the past day. It lights up ( specifically the green "ON" and orange "L" LED's) but no code seems to upload to it and my computer won't even recognize it, I've checked my firmware and device manager, but it still has not been recognized by my computer. I dummy checked my computer with an arduino UNO, and it instantly recognized it, using the same port and cable. My only thought is that after some years somebody broke something on it, but I really have no clue. My teacher doesn't have any more, and I don't really want to buy one. Any help would be really appreciated!
The only things I can think of is look in the tools and be sure the proper board is selected. Open the terminal and see if you get anything. If that does not resolve it you may have to try to reload the boot loader. You can get china clones for about $10. I would suggest you get two so you have a future backup or maybe you might just want to keep a project. Hint, I always have my code start with a terminal message giving the program name.
Hey! I tried this, but I don't think it works because my computer is not even recongizing the arduino. Like no notification what so ever or even in the device manager. On the other hand, when I connect my uno into the computer with the same port and cable, the uno works perfectly...
