Everyone seems to be very concerned about weather forecasts. Of course, obtaining accurate weather forecasts is very useful for your travel plans and other activities. Weather forecast information can be obtained in many places, such as webpages, most smartphones or tablets. Now you can use the "wether" tool on Raspberry Pi to obtain the weather forecast information through command line."Weather" can be ins

Introduced The DHT11 is a cheap accessory that includes temperature and humidity sensors, and the code is easy to use. This article describes if you use DHT11 in a Raspberry Pi, the code is python. If you have any questions, please leave a comment below. Wiring VCC Connection 5V or 3.3V Data i

Reference: RPi Serial ConnectionThis article from: Http://www.raspberry-projects.com/pi/programming-in-c/uart-serial-port/using-the-uartUsing the UARTIf you is running Raspbian or similar then the UART would be used as a serial console. Using a suitable cable, such as the Ttl-232r-3v3-we, you can connect it to your PC and using some simple terminal software Set to 115200-8-n-1 use the command line interface to the

Linux-Raspberry Pi system partition There are two main partition commands: fdisk and parted.Both commands require the root permission,First, we will introduce the fdisk command: Fdisk allows you to view the usage of the current file system. fdisk -l Because I installed the system on the SD card, the partition starts with/dev/mmcblk0. We can see that there are currently three actual partitions (/dev/mmcblk
