On-line tutorials, general Python with Rpi.gpio to control the Raspberry Pi Gpio, and C + + generally use WRINGPI library to operate Gpio,rpi.gpio too simple, many advanced features do not support, such as I2C/SPI library, etc., but also lack of high-precision timing and other advanced features. In contrast, WIRINGPI is rich in functionality, but in fact WRINGPI

First I want to enable root user, so I first enable root user:Su dopasswd rootYou will be prompted to enter the password two times, and then:Su dopasswd--unlock rootThis allows you to start the root login and if you want to use root immediately, you can:Su RootThis allows you to switch directly to the root user, but will prompt for a password, if the next time you log in with root, you will be logged in the Display Settings screen, if you just play, you can not

As we all know, the relay is a small current to control the operation of a large current "automatic switch", in our lives, work everywhere. Now the "smart home" concept, there are many functional modules is actually "intelligent switch", remote switch, timing switch, condition trigger switch and so on.The Orange Pi one (arm Linux) control relay, described below,
