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 ...

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.

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 ...
