So you have put a negative voltage into your Arduino. Logic says this has blown it up, however if you are lucky you may have got away with it.

Not sure what you mean by 64 char buffer overruns but will look into that too.

Don't bother with that we have found your problem, it's not using a voltage converter / inverter.


ok thanks , i see the tutorial on max 232 and if its like the other ones looks simple enough.

luckily nothing has blown up chip still is working on usb  ;)

Really appreciate the help guys
