双击图标打开 IDE 并用 USB 将 Arduino 连接到计算机后,您需要检查工具菜单,查看 Arduino Uno 是否作为主板列出,以及它连接到哪个端口。在菜单中进入工具/板,并检查板说“Arduino/genu ino Uno”;如果没有,从下拉菜单中选择 Uno。 港口 您将通过其中一个 USB 端口将 Arduino 连接到计算机;这些端口有一个编号,在...
In the diagram below we show an UNO board that has D13 as the LED_BUILTIN value. 如果想用该代码点亮一个外接 LED,需要连接电路,需要将电阻的一段连接到 LED_BUILTIN 常量对应的数字针。连接 LED 的长脚(正极脚,也叫阳极)到电阻的另一端。连接 LED 的短脚(负极脚,也叫阴极)到接地 GND。下面的...
Step 4:And terminal 2 is connected to the A0 pin of the Arduino Uno board. You can read the output from terminal 2 of the potentiometer. How does a potentiometer light up an LED? When you rotate the potentiometer knob, the output voltage is changed, and the Arduino Uno reads this chang...

将 SCL 连接到模拟五( A5 )。将 SDA 连接到模拟4 ( A4 )。它连接到模拟引脚的原因很简单。这些引脚包含I2C协议所需的电路。确保它们正确连接,并且没有交叉。确切的引脚会因型号而异,但是Nano和Uno会使用A4和A5。如果您未使用Arduino或Nano,请查看模型的Wire库文档。
Barobo Starter Kit (Arduino-Uno-Compatible) The Arduino functions and robot functions can work together in a single program. This enables various devices in the Barobo Starter Kit (Arduino-Uno-Compatible), such as push buttons and potentiometers, to be used to seamlessly control Linkbots™ and...
