首先把电阻的一只引脚连接到 LED_BUILTIN 常量所指定的数字引脚,然后把 LED 灯较长的一只脚与电阻相连,最后把 LED 较短的另一只脚(负极、阴极)接到 GND 地。下图我们展示了 UNO 板的接法,而它 LED_BUILTIN 的常量值为 D13。 连接LED 的电阻阻值可以比 220欧更高,只要低于 1K欧 LED 都能点
Add some sizzle to your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection and a capacitive touchscreen. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixel...
选择或者新建一个 Arduino 项目,在右下角找到选择端口的选项。这里需要依据自身的端口设置,并非都是 “COM3”。 设置电路板类型 同样在窗口右下角找到对应的选择板子类型的选项,依据自己的情况进行选择。 编译验证项目 编译项目的快捷键如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 Ctr+Alt+R 或者点...
Arduino Nano是一款非常流行的微控制器板,广泛应用于物联网、嵌入式系统和电子原型设计等领域。它基于Atmel AVR微控制器,具有较小的尺寸和低功耗,适合于在各种项目中进行嵌入式开发。 A...
在Arduino 中,`int led = LED_BUILTIN` 这行代码通常是用来定义一个整数型变量 `led`,并赋值为 `LED_BUILTIN`。这种写法常见于 Arduino 的示例代码和库中,有一些原因可以解释为什么这样写: 1. **可移植性:** - `LED_BUILTIN` 是 Arduino 框架中的一个预定义常量,它表示板载 LED 的引脚号。使用 `LED...

Hi I'm new to arduino and in the process of learning, like many I learn through tutorials, videos , 'ibles and by own experience. Recently I wanted to use arduino Uno and IR remote to control VLC player. Unfortunately this didn't work well for me as Uno does not have built-in USB...
请记住,对于新的 Pico W,这就是您需要对 LED 进行寻址的方式,因为它不再与 GPIO 端口 25 关联,而是使用 Infineon 43439 芯片上的WL_GPIO0 引脚。 将示例集合中的 Blink例子加载到 Arduino IDE 中。我们将按原样使用它,因为它已经使用了“LED_BUILTIN”,它可以与 pour new Pico W 一起使用。 在我们...
