a more complex input with timing. Here are two points to note: The SetMode is in BCM mode, and the pin used is the same as the BCM number corresponding to the pin graph. You can also set the physical PIN number to use SetMode (GPIO). BOARD). The input/output mode is input when receiving data/status relative to host or Raspberry Pi, output i²c I²c can be a bus to

Sensor installation and configuration 1.1 DHT22 installationThe DHT22 is a temperature and humidity sensor with 3 pins, the first pin on the left (#1) is the 3-5v power supply, the second pin (#2) is connec

Raspberry PI Series--bare metal illuminated LED lightsBackgroundRecently just bought Raspberry PI B +, configured to run the official Raspbian system, tossing a week Linux system, feel no meaning, so try to understand the bottom of the start process, through a few days of research, It is found that the boot of the lowe

developers need to build an art-level graphical user interface. QT is easy to scale and allows for real component programming. Basically, Qt is the same type of thing as the MOTIF,OPENWIN,GTK on the X Window and the Mfc,owl,vcl,atl on the Windows platform.To put it simply, QT can write programs that are easily ported to other platforms, basically recompiling the program.install qt on Raspberry PiInstall us

another host. It can be used with the default settings by just specifying a hostname (e.g. ping raspberrypi.org ) or an IP address (e.g. ping 8.8.8.8 ). It can specify the number of packets to send with the -c flag.Nmapnmapis a network exploration and scanning tool. It can return port and OS information about a host or a range of hosts. Running just would display the options available as well as nmap example usage.HOSTNAMEThe hostname command displays the current hostname of the system. A privi

follow this lesson, you need the following devices or software: Hardware section Raspberry Pi Adafruit Control Cable The logic level of this cable is 3.3V so it is safe, but not all kinds of cables are 3.3v! Only use the Adafruit control cable in this tutorial to avoid damaging the gpio pins on the small faction. Software Installation (MAC) OSX has its own ter
