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,如果转换后的整数再转换回字符串与原始字符串相同,则可以认为转换是成功的。 cpp String convertedBackToString =...
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:"...
