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。
RTduino为RT-Thread的Arduino生态兼容层,是RT-Thread社区的下属子社区,旨在兼容Arduino社区生态(如上千种分门别类的Arduino库,以及Arduino社区优秀的开源项目),来丰富RT-Thread社区软件包生态,并降低RT-Thread操作系统以及与RT-Thread适配的芯片的学习门槛。可以让用户 ...
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 ...
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.
[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 ...
