Light-Emitting Diode (LED)(Most LEDs will work) Resistor(220 Ω) Arduino Blink LED Circuit To connect an LED to an Arduino, you need a resistor in series with the LED. This is to limit how much current the LED pulls out of the Arduino pin. The value isn’t crucial but should be b...
In this guide, you’ll learn how to control an RGB LED using the Arduino. An RGB (Red-Green-Blue) LED can produce a wide variety of colors by mixing different intensities of red, green, and blue light. You’ll learn to create a basic Arduino RGB LED circuit and cycle through some ...
在Arduino Uno 板子上,D0 到 D13,以及 GND 接点的位置如下: 认识LED LED 的名称是发光二极体(Light-Emitting Diode),是一种半导体二极体,具有阳极和阴极两个端子,一个 LED 元件的两只接脚长度不同,长的接脚是接正极,短的接脚是接负极,也可以借由塑胶外壳上有平面的那边来识别负极所在: 至于半导体二极体的...

阿杜莱特Ardu(ino)(Ambi)light:基于Arduino的环境光控制器,用于基于WS2801的数字RGB LED像素。示例视频:图片集会可以在找到包括BOM(物料清单)在内的组装说明。由于ATmega32u4的QFP封装,PCB必须通过热空气或回流焊接。接线有关详细的接线指南,请查看。在LED条必须从外部电源供电,例如使用连接器等。您只需连接GND、CLK ...
5. 发光二极管 LED (Light Emitting Diode) 发光二极管是二极管的一种,当然,正常工作时候会发光。 二极管其中一个特性是在正常工作电压下单向导通,它在原理图的符号形状很好地描述此一特性。也因此单向导通特性,市电交流电电路里面是无法使用 LED 的。虽然说单向导通,但电压再加大时候,是可以反向击穿的。另外,所谓正常...
