How to reset the Arduino Nano?

Basically, there are two ways to reset the Arduino Nano: programmatically and electronically.

Programmatical method:

The Arduino Nano comes with an in-built RESET function. The board will reset automatically once this function is called. To reset the Nano programmatically, you can upload the following program:

void(* resetFunc) (void) = 0;

void setup() {

Serial.begin(9600);

Serial.println(“How to Reset Arduino Programmatically”);

Serial.println(“www.TheEngineeringProjects.com”);

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.”);

}
