Safe Shutdown
You may notice there's no such thing as a power button for the Raspberry Pi as for PC.
Most people would directly unplug the power cable for the Raspberry Pi, which may cause
damage to the Raspberry Pi and SD card, data loss, etc. To avoid such issues, you need a
safe shutdown for the Raspberry Pi.
If you just use the Raspberry Pi independently, you may shut it down with the following
command:
sudo shutdown –h now
When the green light stops blinking on the Raspberry Pi, you may unplug the power cable.
If you're applying the Raspberry Pi smart car, you may tab the Exit button in the app of this
product. When the green light stops blinking on the Raspberry Pi, switch to OFF for the
Power switch on Shield and you can shut down the Raspberry Pi then.
