Is it safe to open a GPIO pin for output, and set it to "1" when nothing is attached to the pin? I've been testing an app to detect pin value changing, and I've been just raising (via software) the pin high/low with nothing attached just to test my app. Just making sure it's safe.
My choice would be disconnect or turn off for a major change, minor revisions may well be done live. Certainly testing is best done live. But consider "Oops I didnt mean to connect that there" with "Oops BANG"Secondly,
When I have a circuit on my breadboard and I want to change it up, do most people do this while the Pi is running? Out of fear I've been shutting down my Pi before switching out my projects.
