0. PrefaceThis blog post may not have much use value. But practice for practice. There are many ways to use SQLite on Raspberry Pi, and there are many ways to install it. "1" assumes that Python is used, so you don't have to install SQLite because Python has its own sqlite."2" can be installed using Apt-get. Only the

to the Openhab channel (you need to verify and allow it to access your Myopenhab account) to connect IFTTT. Also note that unless your item has changed at least once, the list of items on the IFTTT will not appear, so if it does not appear, switch the switch and reload.Congratulations, you can now access your Openhab system through IFTTT!Using the Bluetooth status sensor with restOn any other platform, there are ready-made Bluetooth bindings. However, because the Java file needs to be recompile

Objective Last year's Raspberry Pi has been in the drawer to eat ash, the previous array of Debian 9 released, there is no accidental support for the Raspberry Pi. Then re-took out the card reader and re-installed on the Debian Desktop version of the system. Introduced Now this thing is just a little bit more about

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 using the following commandsudo apt-get install

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
