This year during the New Year, I brought back a DIY small server and set it up at home to create a resource sharing service, allowing family members to store and share some photos and videos taken with their mobile phones. However, since I'm not usually at home, if any issues or failures arise, I need to remotely log into the home server to handle them. So the question arises: how can I bypass multiple layers of networks and access
First, unplug the Raspberry Pi's power supply to ensure it is powered off while connecting external devices. If you have the operating system installed on a microSD card, you can now insert it into the Raspberry Pi.
Next, plug in other external devices such as a mouse, keyboard, and monitor.
Finally, connect the power supply to the Raspberry Pi. When the Raspberry Pi powers

1. Overview of Vehicle Detectors
Vehicle detectors primarily target motor vehicles and are used to detect data related to vehicle passage or parking, providing sufficient information for smart parking systems to make optimal decisions.
Magnetic detection is a new vehicle detection technology that primarily uses magnetic resistance sensors (xMR) to sense the magnetic field within its range, thereby distinguishing vehicle situations. Currently, magnetic vehicle detectors predominantly
This article attempts to briefly outline the development history of ARM processors, the evolution of their architecture, including the application directions of different processors. However, we will focus on the Cortex-A series and also introduce the inheritance relationships between different microarchitectures, as well as which design teams they originated from. This will likely be a series, covering an overview of the development of ARM processors and architectures, ARMv7-A architecture and microarchitecture analysis, ARMv8-A architecture and microarchitecture analysis, key technologies

It is an Arduino UNO board without any circuit board.
It uses a technology called freeform to interconnect components using wires or copper instead of a circuit board. It looks minimalistic and beautiful!
Why did I make this? I often find it hard to explain what freeform electronics are and what they look like. And Freeduino is a great example of freeform electronic art,

Project Name: [Air Mouse][Gesture Control] BlueGo
Project Author: Geek Fantasy
I developed an ESP32 based “Air Mouse + Gesture Control” called BlueGo, which is even better than a mouse!
Let's scroll down to see its featured functions!
Function Demonstration, Hardware Description, Assembly Instructions,Design Diagram,Open Source Material Download, Conclusion
BlueGo can connect to mobile phones,tablets,TVs,computers via low-power Bluetooth, and perform air mouse, gesture interaction, and
Hello everyone, I am a 30-year-old uncle who started learning programming, DF Maker Community ID: jd3096. I am fortunate to participate in DFRobot's call for Raspberry Pi project activities.
As a self-taught MicroPython learner for two and a half years, this is also my first attempt to use Raspberry Pi Pico for a project. I hope
The Raspberry Pi is currently the most popular single-board computer. You can use it in your DIY projects, or as a cost-effective system to learn programming, or for your convenience, run a streaming software on it as a streaming device.
You can do a lot with the Raspberry Pi, but it is
This project uses an Arduino UNO board connected to the MAX30102 module (pulse oximeter and heart rate monitoring module), along with an OLED display and a buzzer for BPM measurement.
BPM stands for "beats per minute", which is about 65-75 for a normal person at rest, and may drop below this during sports activities. SpO2 indicates the oxygen saturation level, which is generally above 95% for a normal
