Arduino重置

三种方式手动重启Arduino

1.Arduino板上重新编写代码时，Arduino将重新设置
2.Arduino软件中打开串行终端，同时将Arduino板连接到计算机。打开串行终端时，Arduino会自动重置
3.按下复位按钮

两种方式自动重启Arduino

1.使用Arduino板上的RESET引脚以编程方式重新设置Arduino，就是利用一个数字口，代码运行到那的时候就将REST置低
这里利用数字口D2

int Reset = 2;void setup() {    digitalWrite(Reset, HIGH);  delay(200);   pinMode(Reset, OUTPUT);       Serial.begin(9600);  Serial.println("How to Reset Arduino Programmatically");  delay(200);}void loop() {  Serial.println("A");  delay(1000);                 Serial.println("B");  delay(1000);                 Serial.println("Now we are Resetting Arduino Programmatically");  Serial.println();  delay(1000);  digitalWrite(Reset, LOW);  Serial.println("Arduino will never reach there.");}

2.不使用任何硬件引脚，Arduino有一个名为resetFunc（）的内置函数，我们声明函数地址为0，当我们执行此功能时，Arduino将自动重置。

说明：
–In this method, we are not gonna use any hardware pin, instead we will do everything in programming.
–Arduino has a builtin function named as resetFunc() which we need to declare at address 0 and when we execute this function Arduino gets reset automatically.
–So, no need of doing anything in hardware and simply upload the below code in your Arduino board.

void(* resetFunc) (void) = 0;void setup() {       Serial.begin(9600);  Serial.println("How to Reset Arduino Programmatically");  delay(200);}void loop() {  Serial.println("A");  delay(1000);                 Serial.println("B");  delay(1000);                 Serial.println("Now we are Resetting Arduino Programmatically");  Serial.println();  delay(1000);  resetFunc();  Serial.println("Arrduino will never reach there.");}
