首先，按照电路图把Arduino插接到面包板上，连接电阻器和电容器后接通5V电源。 其中，Arduino的#2数字引脚先通过一个330欧姆电阻器，再通过跳线连接到LED灯带中间的Din引脚。

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。

8x8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8x8 LED Matrix module ...

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds ...

Chapter 1, page 11 This code is basic but allows the reader to gain insight into key elements for several other projects in this book. It combines two pieces of code that are listed in the examples ...

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 … ...

This was controlled with an Arduino Uno. The LED matrix was mounted inside the shadow box, behind the vellum paper. The Arduino code was easily written using Adafruit’s RGB Matrix Panel library.

The engineers at Anaveo Labs have created a new Arduino LED controller allowing you to customize the lighting of up to 300 LEDs. The small LED controller comes with its own companion smartphone ...

The power LED is on because, well, the Arduino has power! Why is the other LED blinking? Because the Arduino is executing the pre-installed software called Blink.

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 ...
