Receive the data between 0 to 9 serially using arduino.

Here i am using online IDE Tinkercad . If you don't know what is tinkercad then refer my blog HERE or else you can use offline IDE also.

Code :-

void setup()

{

  Serial.begin(9600);

}

int i =0;

void loop()

{

  if(Serial.available()){

  i =Serial.read();

  delay(600);

  Serial.print("Number is : ");

    Serial.write(i);

  Serial.print("\n");}

}

Output :-
