String inputString = Serial.readString(); 使用Arduino的 toInt() 函数将字符串转换为整数: Arduino的 String 类提供了 toInt() 方法,可以将字符串转换为整数。 cpp int number = inputString.toInt(); 验证转换结果是否正确: 在转换后,你可以通过比较转换前后的值
int inChar = Serial.read(); if (isDigit(inChar)) { // convert the incoming byte to a char // and add it to the string: inString += (char)inChar; } // if you get a newline, print the string, // then the string's value: if (inChar == '\n') { Serial.print("Value:"...
String Replace: Replace individual characters in a string. String Start With Ends With: Check which characters/substrings a given string starts or ends with. String Substring: Look for "phrases" within a given string. String To Int: Allows you to convert a String to an integer number.纠错...
servo1Pos = dataInS.toInt(); // Convert the string into integer 在这里我们可以简单地调用write()函数并且伺服将转到该位置,但是以这种方式伺服将以其最大速度运行,这对于机械臂来说太快了。相反,我们需要控制伺服的速度,因此我使用了一些FOR循环,以便通过在每次迭代之间实现延迟时间来逐渐将伺服从前一个位置...
