backup to prevent a hard disk from being damaged.Prepare Hard Disk The initial step is to format the hard disk on the desktop. This is for convenience. If something goes wrong, we can remove the hard disk from the NAS and read the data on a PC. It can be formatted on Raspberry Pi, but it will take several hours to format it much faster from the desktop. Do it now. Set SSH to enable the root user. First, set the password for the root user:Sudo-IPasswd root(Enter your password) Run the

Raspberry Pi advanced GPIO library, wiringpi2 for python Use note (3) GPIO operations, gpiowiringpi2 The core function of the GPIO library is to operate GPIO. GPIO is the "general input/output" interface, such as lighting up an LED or relay, or using iic spi 1-wire and other protocols, reading and writing data are all useful for GPIO. It can be said that without GPIO, Raspberry Pi can only be used as a small computer. With GPIO, it will be upgraded to a controller. Let's talk about how to operat
