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 b...
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...
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: ...
