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来验证转换是否成功。例如,如果转换后的整...
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:"...
The given code can be summarized as follows: A string variable "a" is assigned the value "1200" and an integer variable "num" is declared. The setup function initializes the serial communication and converts the string "a" to an integer using the toInt function. The converted integer is ...
