A float is a data type in Arduino that can hold decimal values. floats can store much larger values than int between (-3.4028235E38 to 3.4028235E38) but require more memory to store. How to Convert int to float in Arduino Now that we have a basic understanding of int and float, let’s...
// then the string's value: if (inChar == '\n') { Serial.print("Value:"); Serial.println(inString.toInt()); Serial.print("String: "); Serial.println(inString); // clear the string for new input: inString = ""; } } } [Get Code] 更多 String object – 字符串对象的参考 C...
void loop() {}Store Long into Arduino EEPROMNow that you’ve seen how things work for an int number, well, good news for you: it will be almost the same for the long data type.For a long number, you have 4 bytes instead of 2.Here’s a code example working for long numbers.void...

实现了类型转换,主要使用 stdlib.h 中的 itoa() 函数来实现。在C语言编译环境下,需要导入#include <stdlib.h>库,但是Arduino IDE中不需要进行导入库。 函数itoa()原型 char *itoa(int value, char *string, int radix); 原型说明: value:欲转换的数据。
