Although the Raspberry Pi has gcc, you can compile the C + + program, but if the project is large, compiling with the Raspberry Pi will waste a lot of time, we can compile the program on the PC, then pass the executable file to the Raspberry Pi, execute the program, make full use of the resources on the PC and speed up the development progress. First need t

TargetPress the button in the mobile app to open the bedroom door.Basic principleRaspberry Pi as a control device: It runs a Linux system, so it is powerful and provides a GPIO interface, so it is easy to control the physical door mechanism.Yeelink Platform as a cloud provider: it is very difficult to build your own Web server, Yeelink provides free internet of things cloud services, and open APIs that can be used to write mobile apps.Register a switc

If you're bored with a smart home that just has to download a specific app to control a light, here's the good news: Openhab can give you the most flexible control of smart home, Openhab is a mature, open source home automation platform that can run a lot of software, There is no agreement, which means it can now be connected to almost all of the home automation hardware on the market.Here we will show you how to install and launch the free smart home system.We first use Raspberry

first, the simplest method on the Raspberry Pi is to use apt-get and then give control to the Openhab user.sudo apt-get install openhab-addon-binding--hr Openhab:openhab/usr/share/openhabNext, you need to tell Openhab to load the binding and configure all the required variables. go to the configuration folder, copy a copy of Openhab-default.cfg, and name it openhab.cfg. Open the file, search for hue, and replace the entire section with the following

Calculation of Pi by Monte Carlo methodA few days ago read a blog: Introduction to Monte Carlo method,http://www.ruanyifeng.com/blog/2015/07/monte-carlo-method.htmlIt introduces the method of using probability to calculate pi, so the following attempts are made with the program.The approximation of the PI value as a constant is 3.141592653589793 in Math.PI.Ⅰ.

Today when I tried to connect the Raspberry Pi with SSH, I found that the Raspberry Pi did not open the SSH service.I don't have a monitor, I don't have an external keyboard.So, I pulled the Raspberry Pi hard drive (memory card) and plugged it into the computer, and I added it in the/etc/rc.local exit 0./etc/init.0/ssh startThen the memory card plugs back into th

When you log on to Raspberry Pi and open a terminal window, or you replace the graphic user interface and start directly to command line mode, you will start in the home directory. If your user name is Pi, the path is/Home/PI. This is where the user saves the user's own files, including the folder desktop where the user saves the files on the desktop, and some o

To run a command or program when Raspberry Pi is started, you need to add the commandRC. LocalFile. This is useful when you want to run the program directly without configuring it after Raspberry Pi is powered on, or do not want to start the program manually every time. Another method to replace a scheduled task is to use cron and crontab. Editing RC. Local (edit the RC. Local file) On your Raspberry

make these aliases take effect later. Command lines starting with "#" are commented out. To enable them, you only need to remove "#" And wait until your Raspberry Pi starts to activate these settings. The. bash_aliases file is also referenced here. By default, this file does not exist: If [-f ~ /. Bash_aliases]; then.~ /. Bash_aliasesFi The if condition is used to check whether the file exists between the imported files. You can create this. bash_ali
