What I would like to do, is to let the Raspberry Pi run and while it is running, connect and disconnect eg. sensors whenever I please to/from the breadboard WITHOUT turning off/disconnecting the Pi from the breadboard.
As far as I know, there could be trouble because of the unregular voltage and in the worst case, the Pi would get killed. Is there a piece of hardware which enables me to do so? I have heard about giving an external source of electricity for the breadboard but I am looking for something different, something more "mobile".
