Hello everyone, The + lead of my 6 AA batteryholder with 6 AA NiMH batteries in it (a total voltage of 7.2 V) accidently has be connected to my Arduino' s Digital pin 0 (the RX Serial pin) . Is it damaged now? I didn't connect the - lead to the Arduino Board. Kind Regards, Superpelican =(

Is my RX pin damaged?

Yes, if only one lead was connected to anything then there's no path for current to flow.
