===========================================
==	Proper C Code for Arduinos
==	Turning on / off an LED
===========================================

void setup()
{
  //Code to run once at the start

}


void loop()
{
  //Code that runs over and over repeating

}


COMMANDS
===========================================
pinMode(pinNumber, INPUT or OUTPUT);

Example:

pinMode(4, OUTPUT); //This makes digital pin 4 an output pin


===========================================
digitalWrite(pinNumber, HIGH / LOW);

Example:

digitalWrite(4, HIGH); //Sends a 1 signal to that pin, for powering an LED or something

digitalWrite(4, LOW); //Sends a 0 to in 4.  This would turn off an LED for example.


===========================================
delay(milliseconds);

Example:

delay(1000); //Will delay the program for 1 second
delay(500); //Will delay for half a second
delay(3000); //Will delay for 3 seconds

Blinky light Example Code

void setup()
{
    pinMode(4, OUTPUT);
}


void loop()
{
    digitalWrite(4, HIGH);   //Turn on the LED
    delay(1000);               //Wait a second
    digitalWrite(4, LOW);   //Turn off the LED
    delay(1000);              //Wait another second before repeating
}

Write a program that blinks out an SOS

Thats 3 quick blinks + 3 Slow blinks + 3 More quick blinks
