Hello there,
I am working with an Arduino Mega 2560 for the first time for a university project. I don't know if this Arduino is new or old or if anyone has used it because my professor lent it to me. I haven't been able upload any code, including Blick, to the Arduino at all. I'm using Windows 8.1.
I have tried:
-Using the installed Arduino IDE AND the web editor
-Using another laptop with Windows 10
-Plugging the USB cable to different ports on my laptop
-Using a different USB cable
-Reinstalling the Arduino IDE
-Uploading different codes
-Choosing the correct Board, Processor and Port (COM 3) under Tools.
-Pressing the reset button on the Arduino before trying to upload the code.
Nothing worked for me so far.
The "L" LED blinks and so does the "TX" LED after trying to upload the Blink. When I go to Tools > Ports > Serial Ports, Serial Ports is greyed out. I'm not sure if that is a problem.
I have read numerous forum posts mentioning burning the bootloader but I can't find detailed instructions on how to do so. Someone mentioned flashing the firmware. I have no idea what that means or how to do it. Googling did not help.
I would prefer a solution that does not involve another piece of hardware as this is the only arduino I have..
Any help ASAP would be greatly appreciated. Thank you so much. Have a great day.
I got this error message:
