The Arduino® hardware runs the application created from your model in the flash memory. The application resides in the flash memory, even after you disconnect the power from the hardware.
To stop an application running on Arduino hardware, you can:
Disconnect the power from the hardware. When you reconnect the power, the hardware starts running the application again.
Alternately, run a new or updated application on the hardware. This action automatically stops and erases the previous application running on the Arduino hardware.
To restart the model running on the Arduino hardware, press the RESET button on the board.
