    Random thoughts, but without anything plugged in, the signal may drift high or low. But when you plug something in, things will look different.

    Perhaps you could detect the sudden change of signal pattern?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
