The Raspberry Pi does not have a battery, so the system time stops after the power outage, until you start the timer again.Because the project needs to use local time, the accuracy requirements are not high do not want to toss (if you need high precision, need to install NTP), so consider using Python script synchronization Baidu time, accuracy error is small in

The Python request library periodically uploads temperature information to the yeelink platform and modifies RC. the local script enables the Python script to run in the background at startup, and reports the tempe

When I run this script, I log on to a Raspberry Pi and enter "sudo reboot" to restart the

Raspberry Pi backup and Raspberry Pi backup We strongly recommend that you regularly back up important files. Backup is usually not limited to user files, but also configuration files, databases, installed software, settings, and even system snapshots. Here we will guide you through some backup technologies to back up

0 PrefaceThis article reads Raspberry Pi CPU temperature through file operations. In Linux, any device operations are abstracted as file read/write, read the content in the/sys/class/thermal/thermal_zone0/Temp File to get the Raspberry Pi CPU temperature. This article describes how to read and apply the temperature par

using a PIN, the user needs to find the corresponding rule between the channel number and the physical PIN number. For different Raspberry Pi versions, the script files you write may not be generic.For example, the "GPIO 16" and "36" pins refer to the same, while the corresponding ones are defined by BCM, which is defined by "BOARD".V.

In my previous article, I talked about how to build a high-availability system: Two Raspberry Pi deploy the GlusterFS cluster file system, and it becomes a fault-tolerant file server. In this article, we will build another Fault-Tolerant Service Based on this high-availability system: Build a simple Web server cluster.
