Arduino Uno,Arduino Nano的Serial通讯引脚为0,1号引脚,进行Serial通讯时这两个应交将被占用。 常用库函数 Serial 1.begin(longspeed) 功能:设置串行数据传输的比特率(波特率)。 参数:speed表示比特率。若要与Arduino IDE自带的串行监视器通信,须确保speed的值为屏幕右下角菜单中列出的波特率之一。 2.print(val, ...
Arduino板可以通过pinMode(pushButton, INPUT_PULLUP);启用内部上拉电阻,这样就不需要外部上拉电阻了。 Arduino板: 确保Arduino板通过USB线连接到电脑。 运行结果 打开ArduinoIDE的串行监视器(波特率设置为9600),按下按钮时,串行监视器会显示0(表示按钮被按下,引脚为低电平);松开按钮时,串行监视器会显示1(表示按钮...
int sensorValue = analogRead(A0); // print out the value you read: Serial.println(sensorValue); delay(1); // delay in between reads for stability } 这段代码是Arduino编程语言编写的,用于读取模拟输入引脚A0上的值,并通过串行监视器(Serial Monitor)打印出来。 代码功能 读取模拟输入:代码通过连接到...
