In recent years, robotics has witnessed significant advancements, enabling the creation of intelligent machines that can interact with the environment. One exciting application of robotics is the ...

You can use it as a regular USB webcam on Windows, macOS, or Linux PCs, but Arduino’s new plug-and-play accessory is ...

In the previous chapter, we learned about "functions," which allow us to give names to groups of processes. This time, we will learn how to make the Arduino remember its current state. Let's try ...

In the previous chapter, we confirmed that normal sketch processing does not proceed to the next line while waiting with delay(). This time, we will use **millis()**, which can retrieve the elapsed ...

This project blinks an LED at a fixed interval and prints each state change to the Serial Monitor. It was built for the Project Management course (Course Code: 2307476T, CO2) to demonstrate how GitHub ...

Digital clocks are one of the most popular Arduino projects, and most of them use traditional seven-segment displays to show the time. While these displays are simple and reliable, they usually have ...

Nanobodies are extremely small antibody fragments that bind to specific molecules. When nanobodies are labeled with dyes, ...

There are some projects that seem at first sight to be easy, but anyone who tries them finds a whole heap of unexpected problems and turns to the off-the-shelf device. PCB antennas for example, or ...

Design with STM32C5 invites engineers, makers, and talented students to turn their ideas into innovative projects.

本文基于 Johnny-Five 官方示例文档 docs/led-array.md 与对应示例 eg/led-array.js ，系统讲解如何通过 Leds 集合类一次性控制多个 LED，实现同步脉冲、渐隐渐显、闪烁等效果。读完本文，你将掌握 Leds 的初始化方式、方法转发与回调协调的底层机制、PWM 引脚约束，以及如何结合实际接线在 Arduino 等开发板上 ...

这个标题覆盖了两种常见场景：一是Python作为上位机，通过串口和Arduino通信，让Arduino去执行硬件操作；二是Python直接跑在树莓派上，通过GPIO引脚控制LED、传感器、摄像头和继电器等外设。适合谁看呢？包括刚接触硬件开发的Python程序员、想要做智能小车或智能家居项目的学生、以及工作中需要快速 ...
