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。

当环境光线变亮时，又自动关闭灯带。 连接 Arduino ↔ LDR 分压 ↔ 继电器模块 ↔ 12V 灯带。 热熔胶枪（可选） 用于固定 LDR 位置或整理线材，提升结构可靠性。 A0 点的电压随光照变化而变化，Arduino 通过 analogRead(A0) 读到 0–1023 之间的数值，即可反映当前亮度。

This 8x8x8 LED cube with 512 LEDs takes the old 3x3x3 light cube made up of 27 LEDs to the nth degree. This, certainly more time consuming project, actually involves a simpler design. By using a ...

Have you ever wanted to create your own electronic games console? You might be interested in the new DigiPixel Arduino LED game shield which is definitely worth more ...

Sometimes, you just want to go big. Case in point, Make’s guide to make your gigantic, Jumbotron-esque LED video screen. The project here is powered by a Teensy microcontroller, a bunch of LED strips, ...

This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a potentiometer and you can also set a minimum and ...

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 ...

[Alex] needed a project for his microcomputer circuits class. He wanted something that would challenge him on both the electronics side of things, as well as the programming side. He ended up ...

Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to squeeze out ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
