导语：昨天介绍了如何用柠檬做个LED灯，如果你觉得那个too simple，不防尝试用Arduino来控制RGB LED灯吧。 昨天介绍了如何用柠檬做个LED灯，如果你觉得那个too simple，不防尝试用Arduino来控制RGB LED灯吧。 这一步比较随意，将LED灯接到面包板任何地方都行，不过灯的 ...

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 ...

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。

Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some text or picture for ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

Arduino enthusiasts or those looking to learn more about electronics and programming may be interested in and awesome new electronics kit that allows you to create a full colour LED flashlight which ...

[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 ...

From your very first blinking LED to dazzling multi-color sequences, Arduino makes it easy to bring light to life. With just a board, a few LEDs, and some code, you can experiment with patterns, ...
