Just like in algebra, one of the first thing you must know in programming is how variables work. I am sure you understand, but if you don't, a variable is a letter or symbol that can represent any number. In C++, they can also represent things such as words or characters, but we will get into those later. Lets run through the most basic types of variables: int x; X is now an integer so it can be negative or positive, but NOT a decimal. double x; X can now be negative, positive, AND a decimal. char x; X can now be any one character like Y or H. char's are NOT values, so you CANNOT do any sort of mathematical operation with them, like this: char x = 10; char y = 5; x + y = z; z = 15; WRONG!!! but you CAN do this: char y; char x = 'h'; y = x; Now y = "h" because x = "h" and we said y = x; But now we need to understand how to assign values or characters to these variable types! For int: int x; x = 5; OR in

In almost all programming languages, the first program that people learn is how to print "Hello, World!" to the screen. So this is what we will be doing now in c++! So we start off  by doing this: #include <iostream> using namespace std; This basically says that we will be using the iostream library to be able to print things out to the console. don't worry about using namespace std; for now. int main() { return 0; } This is the function where everything will happen ( everything inside the brackets.) the return 0; is what we need to include at the end of the function because main is an int function. We just return 0 to show that the function has ended. cout << "Hello World!!!" << endl; This will go inside int main(). All this does is prints out Hello World!!! on the console, and endl just ends the line after that. Remember to include that semicolon at the end of cout. Your final code should look like this: #i

Hey guys, axtyax here! and today we will be beginning c++! C++ is probably the most powerful programming language out there, and is constantly updated! Some of the uses of c++ are Video games Commercial applications, for math or even analytics Mobile applications microcontrollers such as the arduino and much much more  So now that we have a basic understanding on why c++ is an optimal language, lets get started! *WARNING c++ is not simple, but with some practice, you can make so many on your computer that you will regret not having starter c++ sooner! So when we start out our program we need to declare all of the libraries we will be using. think of libraries like a group of many tools for c++ that are made to be utilized by the user, without any libraries, displaying simple text on the screen would be VERY difficult. right now, though, the only library we will use is call iostream iostream just creates the stream of input and output from the console window

Arduino tutorial: Fading LED   Hi, Axtyax here, and now we will now learn how to make an LED fade out or in with an arduino! you will need: Solderless Breadboard (if you dont know what this is, look it up) Wires An arduino The arduino cable to connect it to your computer A computer with the arduino IDE  Im not completely sure, but i think you will need an 820ohm 1/8w resistor (if you know of better specs for the resistor, just comment please) And finally, an LED.  Use this schematic to wire up the circuit: Now lets have a look at the code:  -------------------------------------------------------------------------------------------------------------- /*  Fade  This example shows how to fade an LED on pin 9  using the analogWrite() function.  This example code is in the public domain.  */ int led = 9 ;           // the pin that the LED is attached to int brightness = 0 ;     // how bright the LED is int fadeAmount = 5 ;     // how ma

Blinking LED: HI, Axtyax here! Now that you have gotten your arduino and IDE, you are ready to start exploring the world of arduino! Things You Will Need Solderless Breadboard (if you dont know what this is, look it up) Wires An arduino The arduino cable to connect it to your computer A computer with the arduino IDE  Im not completely sure, but i think you will need an 820ohm 1/8w resistor (if you know of better specs for the resistor, just comment please) And finally, an LED.  This is a visual representation of how to wire up your circuit that i made in an application called fritzing, which you should definitely download from this link to create schematics for any of your arduino projects. Ok so now that you have wired up the arduino and resistor and LED, lets get started on the code! This is the code: ----------------------------------------------------------------------------------------- /*   Blink   Turns on an LED on for one sec

Now that you have bought the arduino board (make sure you bought the arduino UNO) , let's get the IDE! This is a link to download the IDE: http://arduino.cc/en/main/software IDE stands for Integrated Development Enviorment, which is basically a programming suite for you to perform certain tasks easier. So in this case we will be trying to program our arduino! Go look at this tutorial for your first project with the Arduino: http://arduino.cc/en/tutorial/blink Make sure you hit build and run when you have it all set up!
