Our Company
Preface
Established in 2011, Elegoo Inc. is a thriving technology company dedicated to open-
source hardware research & development, production and marketing. Located in
Shenzhen, the Silicon Valley of China, we have grown to over 150+ employees with
a 10,763+ square ft. factory.
Our product lines rang from DuPont wires, 2560 R3 boards to complete starter kits
designed for customers of any level to learn Arduino knowledge. In addition, we also
sell products of Raspberry Pi accessories like 2.8’’ TFT touch and STM32. In the
future we would devote more energy and investment to 3D printer products and so
on. All of our products comply with international quality standards and are greatly
appreciated in a variety of different markets throughout the world.

Our Tutorial
This tutorial is designed for beginners. You will learn all the basic information about
how to use Arduino controller board, sensors and components. If you want to study
Arduino in more depth, we recommend that you read the Arduino Cookbook written
by Michael Margolis.
Some codes in this tutorial is edited by Simon Monk. Simon Monk is author of a
number of books relating to Open Source Hardware. They are available in Amazon:
Programming Arduino, 30 Arduino Projects for the Evil Genius and Programming the
Raspberry Pi.

Lesson 0 Installing IDE
Introduction
The Arduino Integrated Development Environment (IDE) is the software side of the
Arduino platform.
In this lesson, you will learn how to setup your computer to use Arduino and how
to set about the lessons that follow.
The Arduino software that you will use to program your Arduino is available for
Windows, Mac and Linux. The installation process is different for all three platforms
and unfortunately there is a certain amount of manual work to install the software.
STEP 1: Go to https://www.arduino.cc/en/Main/Software and find below page.
The version available at this website is usually the latest version, and the actual
version may be newer than the version in the picture.

STEP2：Download the development software that is compatible with the operating
system of your computer. Take Windows as an example here.
Click Windows Installer.
Click JUST DOWNLOAD.

Also version 1.8.0 is available in the material we provided, and the versions of our
materials are the latest versions when this course wasmade.
Installing Arduino (Windows)
Install Arduino with the exe. Installation package.
Click I Agree to see the following interface
Click Next
You can press Browse… to choose an installation path or directly type in the
directory you want.

Double-click to enter the desired development environment
You may directly choose the installation package for installation and skip the
contents below and jump to the next section. But if you want to learn some methods
other than the installation package, please continue to read the section.
Unzip the zip file downloaded, Double-click to open the program and enter the
desired development environment

However, this installation method needs separate installation of driver.
The Arduino folder contains both the Arduino program itself and the drivers that
allow the Arduino to be connected to your computer by a USB cable. Before we
launch the Arduino software, you are going to install the USB drivers.
Plug one end of your USB cable into the Arduino and the other into a USB socket on
your computer. The power light on the LED will light up and you may get a 'Found
New Hardware' message from Windows. Ignore this message and cancel any
attempts that Windows makes to try and install drivers automatically for you.
The most reliable method of installing the USB drivers is to use the Device Manager.
This is accessed in different ways depending on your version of Windows. In
Windows 7, you first have to open the Control Panel, then select the option to view
Icons, and you should find the Device Manager in the list.
Under ‘Other Devices’, you should see an icon for ‘unknown device’ with a little
yellow warning triangle next to it. This is your Arduino.

Right-click on the device and select the top menu option (Update Driver Software...).
You will then be prompted to either ‘Search Automatically for updated driver
software’ or ‘Browse my computer for driver software’. Select the option to browse
and navigate to the X\arduino1.8.0\drivers.
