Arduino Tutorial

Here is the code to copy & paste into the Arduino Software:

void setup() {

// put your setup code here, to run once:

pinMode(13,OUTPUT); // 1

}


void loop() {

// put your main code here, to run repeatedly:


int delayTime = 1000; // 2

digitalWrite(13,HIGH); // 3

delay(delayTime); // 4

digitalWrite(13,LOW);

delay(delayTime);

}

/* Try it:

* 2 - Try changing the number here, see what happens if you make it bigger or smaller

* See if you can program the RedBoard to make the LED blink "SOS" in morse code (dot dot dot line line line dot dot dot)

* Hint: copy and paste sections of code so you don't have to retype everything

*/


/* What's actually happening?

* 1 - This is taking a port on the RedBoard and specifying whether it wants the port to GIVE a command (input) or RECEIVE a command (output)

* 2 - This is taking a random word, and assigning a number to it. So when I reference the word later on, the computer knows I am refering to a number

* Think of it as I take a box and write the words "delayTime" on it then put the number 1000 in it, when I use the words later, the computer takes the number out of the box to use

* 3 - This line specifies how much power should be flowing through the port, HIGH means a lot of power, LOW means no power

* 4 - Delay stops the code for a variable amount of time, the input is read in miliseconds
