这段代码用于读取连接在数字引脚2上的按钮(pushbutton)的状态,并将结果通过串行监视器(Serial Monitor)打印出来。 /* DigitalReadSerial Reads a digital input on pin 2, prints the result to the serial monitor This example code is in the public
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 moni...
Serial.println(sensorValue); delay(1); // delay in between reads for stability 在两次读取间延迟,以保持稳定性 } 2、模拟串口读取 - Analog Read Serial (1)原文地址 https://www.arduino.cc/en/Tutorial/BuiltInExamples/AnalogReadSerial (2)模拟串口读 - Analog Read Serial This example shows you ho...
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...

Serial.read( )// 读取串口缓冲区 1 个 Byte 的数据，不带参数，返回 int 型。// 反复读取串口数据直到读完（Serial.available()=0）时止 5.实验 任务：用 LCD 实现自动滚屏显示、从左向右或从右向左显示、光标任意定位与闪烁等显示功能 电路图：原理图：#include <LiquidCrystal.h> // 包括库函数的头...
int blue = Serial.parseInt(); 一旦你把数据读到你的变量,检查是否有新的字符需要继续读取: if (Serial.read() == '\n') { 用constrain(),你可以使这些值保持在PWM控制的范围内。用这种方式,如果这些值超过PWM的范围,它将会限制在一个可行的数值。从255里减去这个数值,你就可以得出用来控制LED灯的值。
Serial.println(sensorValue); 现在,当你打开Arduino IDE的串口监视器,你会看见“0”的数据流(如果开关打开)或者“1”的数据流(如果开关闭合) /* DigitalReadSerial Reads a digital input on pin 2, prints the result to the serial monitor This example code is in the public domain. ...
Serial Event example When new serial data arrives, this sketch adds it to a String. When a newline is received, the loop prints the string and clears it. A good test for this is to try it with a GPS receiver that sends out NMEA 0183 sentences. ...
