In this video you will learn how to print "Hello world!" in the Arduino IDE. You will learn how to do this one of two ways, using the void setup function and the void loop function. Typically, you will be using the void loop function to print, as you would like to be able to check values in real time. This print of "hello world!" uses C / C++ code in the Arduino IDE.

Feel free to type the code yourself, or find the code on Pastebin

Although printing is the most basic thing you can do in Arduino, it is a vital part of debugging, as well as displaying values being read by the Arduino.

Are you a beginner to arduino? Well, first and foremost, welcome to the arduino community! Arduino is an open source prototyping device. Arduino uses the Arduino IDE, which takes the programming language C / C++. There are many types of Arduinos, the most popular being Arduino Uno, Arduino Mega and Arduino Nano. For the purposes of this series, we will only be using the Arduino Uno.

In the Intro to Arduino series, you will learn how to use the most basic Arduino components. That includes
+ Printing with the Arduino IDE
+ Using LEDs with Arduino Uno to Blink
+ Reading Distance Values of Ultrasonic Sensor with Arduino Uno
+ Making Buzzers make beep with Arduino Uno
+ Rotating Servo Motors with Arduino Uno
+ Using Bluetooth Module with Arduino Uno to Communicate With Your Cellphone
