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。

Our project is infact an Arduino with Serially Interfaced MAX7219 Operates an 8X8 LED Matrix to display a heart pattern. The MAX7219 IC is a serial input/output common-cathode display driver that ...

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 ...

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 … ...

The on-board 12 x 8 (96pixel) matrix of red LEDs (photo right) is Charlieplexed for pixel-level addressing. Arduino_LED_Matrix API is available for programming and control, and “we have developed a ...

A Light Emitting Diode (LED) should light up once the Arduino has power and after a second or so, an LED on the board should start slowly blinking. The image below points out these LEDs on the board.

Learn how to control and blink multiple LEDs using the MAX7219 driver with Arduino. A simple guide for beginners in ...

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 ...

When you read “Arduino wristwatch”, you fall into the trap of envisioning an Arduino UNO clumsily strapped to someone’s wrist. [Marijo Blažević’s] creation is much more poli… ...
