hello world:


void setup() {
Serial.begin(9600);
}

void loop() {
Serial.println("Daniel Graig is the best Bond!");
delay(1000); 
}



Next, we want to decode the inputs and print them out as ASCII characters, 
instead of integers. This will later allow us to control pins based on input 
characters. Below, the input can be decoded by first reading the input as a 
“char” and then printing that “char” variable just as above:

void setup() {
  Serial.begin(9600);
}

void loop() {
  while (Serial.available()){
    char in_char = Serial.read();
    Serial.println(in_char);
  }
}
