A dead man's switch is a device used as a fail-safe. These switches are usually used as a form of fail-safe where they stop a machine with no operator from a potentially dangerous action or incapacitate a device as a result of accident, malfunction, or misuse.
I'm looking for some method to stop an Arduino to prevent harm. Is there an Arduino code sequence that will stop an Arduino and the only way to recover is to restart the device?
