Hello World!

void setup() {
}

void loop() {
  Serial.println("Hello World!");   //sends a message to the computer
}

Simple Led blink example

File:Led-blink.png

int ledPin = 13;               //the int ledPin is 13

void setup() {
  pinMode(ledPin,OUTPUT);      //ledPin is a OUTPUT
}

void loop() {
  digitalWrite(ledPin,HIGH);   //turns pin 13 on
  delay(500);                  //stops the loop for 500 milliseconds
  digitalWrite(ledPin,LOW);    //turns pin 13 off
  delay(500);                  //stops the loop for 500 milliseconds
}

Traffic light example

File:Led-traffic-light bb.png

int RedLedPin = 13;                 //the int RedLedPin is 13
int GreenLedPin = 12;               //the int GreenLedPin is 12

void setup() {
  pinMode(RedLedPin,OUTPUT);        //ledPin is a OUTPUT
  pinMode(GreenLedPin,OUTPUT);      //ledPin is a OUTPUT

}

void loop() {
  digitalWrite(GreenLedPin,HIGH);   //turns green led  on
  delay(5000);                      //stops the loop for 5000 milliseconds
  for(int i = 0; i < 5; i++){       //this for loop gets 5 times repeated
    digitalWrite(GreenLedPin,LOW);  //turns green led off
    delay(500);                     //stops the loop for 500 milliseconds
    digitalWrite(GreenLedPin,HIGH); //turns green led off
    delay(500);                     //stops the loop for 500 milliseconds
  }
  digitalWrite(GreenLedPin,LOW);    //turns green led off
  digitalWrite(RedLedPin,HIGH);     //turns red led on
  delay(5000);                      //stops the loop for 5000 milliseconds
  digitalWrite(RedLedPin,LOW);      //turns red led on
}

Speaker example

File:Speaker bb.png

int speaker = 13;                   //int speaker is 13

void setup() {
  pinMode(speaker, OUTPUT);         //pin 13 is an output
}

void loop() {
  for(int i = 100; i< 1000;i++){    //for loop counts from 100 to 1000
    tone(speaker, i);               //generates a tone on pin 13 with the frequency of int i
    delay(10);                      //stops the code for 10 milliseconds
  }
