Serial.println(buttonState); delay(1); // delay in between reads for stability 延迟1 秒以便稳定读取 } 2、数字串口读取 - Digital Read Serial Read a switch, print the state out to the Arduino Serial Monitor. 读取开关状态,并打印状态到 Arduino 串口监视器。 This example shows you how to mon...
To read data from the serial monitor, first, you need to check whether user entered data or not. To check user data availability, you need to useSerial.available()function/command. When the user enters the data on the serial monitor, Arduino setsSerial.available()to return ‘1’ and in ...
使用前需要先进行设定，设定的方法如下： 1.在Tool==>Serial Port里面选择Arduino的串口编号 2.在Tool==>Serial Monitor里面打开串口监视器 3.工具你程序的设定，在右下角的速度选择框里。
// read from port 0, send to port 1: if (Serial.available()) { int inByte = Serial.read(); Serial1.write(inByte); } } [Get Code] 更多 serial.begin() serial.read() serial.available() if() ASCIITable - 示范使用Arduino的高等的串口输出函数。
// print out the value you read: Serial.println(sensorValue); delay(1); // delay in between reads for stability } (2)代码注释 AnalogReadSerial 串口模拟读取 Reads an analog input on pin 0, prints the result to the Serial Monitor. ...
我们可以运用serial(串口通讯)实现这个功能,主要使用的是serial.println()(自带换行符) 与serial.read()还有serial.available()实现基础功能。我们如果直接使用串口监视器对计算机输出的时候 编程语言 单片机 嵌入式 数据分析 串口 转载 mob64ca1407d5aa 9月前...
Serial.begin(9600); } void loop() { // when characters arrive over the serial port... if (Serial.available()) { // wait a bit for the entire message to arrive delay(100); // clear the screen lcd.clear(); // read all the available characters ...
Serial.println(“Slave Received From Master:”); //Prints in Serial Monitor Serial.println(SlaveReceived); delay(500); lcd.clear(); } 通过旋转一侧的电位器,您可以在另一侧看到LCD上的变化值: 以上就是在Arduino中进行I2C通信的方式,这里我们不仅使用两个Arduino开发板来演示通过I2C通信发送数据,而且还演...
