本文介绍了Arduino代码库的强大功能， 推荐使用Arduino Uno等开发板，并详细说明了如何安装和使用Adafruit NeoPixel库来控制智能可寻址 LED灯带。文章还解释了如何组装电路、编写和修改函数以创建独特的灯光效果，并强调了库在简化设备通信和程序构建中的重要性。

在之前的项目中，我们已经展示了如何使用Arduino来控制LED矩阵。但是，如果您的项目只需要显示数字，那么最好使用七段数码管。这些数码管看起来像复古的数字闹钟，只需要七个LED就可以显示出数字。本指南将向您展示如何完成这个工作。 七段LED数码管的 ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

We’d seen it done with buttons, switches, gestures, capacitive touch, and IR remote, but never like this. [electron_plumber] made an LED that can be blown out like a candle, and amazingly it requires ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...
