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 ...

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 ...

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。

本项目所设计的Arduino 万用表应具备以下功能：·具备3个量程的电压表：0-10V，0-30V，0-100V ·具备1个量程的电流表：0-500mA ·具备2个量程的欧姆表：0-1KΩ，0-250KΩ ·二极管，LED的连接性检测 ·LED功能性测试 ·NPN双极结型晶体管的BETA值测量 首先我必须放出这个警告 ...

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 ...

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.

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 ...

Thank you for completing the survey! This guide will teach you how to run a sample sketch on your Intel® IoT board using the Arduino IDE. These instructions are geared toward the Intel® Edison module ...

[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 ...
