如何在您的项目中添加数码管在之前的项目中，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。

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...

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 ...

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.

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

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 … ...

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 ...

Do this before you sew anything onto your sweater just to make sure the LED string will correctly fit the pattern you drew. Start with the end of the string so the Arduino ends up at the bottom of ...

In a previous article, we looked at connecting various kinds of Arduino hardware to your Mac. Here's how to get started programming on them to create your own projects.
