Page 17 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.
Page 18 Right-click on the device and select the top menu option (Update Driver Software...). 16/78...

Page 20 Click 'Next' and you may get a security warning, if so, allow the software to be installed. Once the software has been installed, you will get a confirmation message. Windows users may skip the installation directions for Mac and Linux systems and jump to Lesson 1. Mac and Linux users may continue to read this section.
Page 21 Installing Arduino (Mac OS X) Download and Unzip the zip file, double click the Arduino.app to enter Arduino IDE; the system will ask you to install Java runtime library if you don’t have it in your computer. Once the installation is complete you can run the Arduino IDE. Installing Arduino (Linux) You will have to use the make install command.
Page 22: Lesson 2 Add Libraries And Open Serial Monitor
Lesson 2 Add Libraries and Open Serial Monitor Installing Additional Arduino Libraries Once you are comfortable with the Arduino software and using the built-in functions, you may want to extend the ability of your Arduino with additional libraries. What are Libraries? Libraries are a collection of code that makes it easy for you to connect to a sensor, display, module, etc.
Page 23 Then the library manager will open and you will find a list of libraries that are already installed or ready for installation. In this example we will install the Bridge library. Scroll the list to find it, then select the version of the library you want to install. Sometimes only one version of the library is available.
Page 24 Finally click on install and wait for the IDE to install the new library. Downloading may take time depending on your connection speed. Once it has finished, an Installed tag should appear next to the Bridge library. You can close the library manager. You can now find the new library available in the Include Library menu.
Page 25 In the Arduino IDE, navigate to Sketch > Include Library. At the top of the drop down list, select the option to "Add .ZIP Library'' You will be prompted to select the library you would like to add. Navigate to the .zip file's location and open it.
Page 26 24/78...
Page 27 Return to the Sketch > Import Library menu. You should now see the library at the bottom of the drop-down menu. It is ready to be used in your sketch. The zip file will have been expanded in the libraries folder in your Arduino sketches directory. NB: the Library will be available to use in sketches, but examples for the library will not be exposed in the File >...
Page 28 Your Arduino library folder should now look like this (on Windows): Documents\Arduino\libraries\ArduinoParty\ArduinoParty.cpp My Documents\Arduino\libraries\ArduinoParty\ArduinoParty.h My Documents\Arduino\libraries\ArduinoParty\examples or like this (on Mac and Linux): Documents/Arduino/libraries/ArduinoParty/ArduinoParty.cpp Documents/Arduino/libraries/ArduinoParty/ArduinoParty.h Documents/Arduino/libraries/ArduinoParty/examples ..There may be more files than just the .cpp and .h files, just make sure they're all there. (The library won't work if you put the .cpp and .h files directly into the libraries folder or if they're nested in an extra folder.
Page 29 Arduinos and other microcontrollers, they decided to include a serial terminal with the software. Within the Arduino environment, this is called the Serial Monitor. Making a Connection Serial monitor comes with any and all version of the Arduino IDE. To open it, simply click the Serial Monitor icon. 27/78...
Page 30 Selecting which port to open in the Serial Monitor is the same as selecting a port for uploading Arduino code. Go to Tools -> Serial Port, and select the correct port. Tips: Choose the same COM port that you have in Device Manager. 28/78...
Page 31 Once open, you should see something like this: 29/78...
Page 32 Settings The Serial Monitor has limited settings, but enough to handle most of your serial communication needs. The first setting you can alter is the baud rate. Click on the baud rate drop-down menu to select the correct baud rate. (9600 baud) Last, you can set the terminal to Autoscroll or not by checking the box in the bottom left corner.
Page 33 Pros The Serial Monitor is a great quick and easy way to establish a serial connection with your Arduino. If you’re already working in the Arduino IDE, there’s really no need to open up a separate terminal to display data. Cons The lack of settings leaves much to be desired in the Serial Monitor, and, for advanced serial communications, it may not do the trick.
Page 34: Lesson 3 Blink
Lesson 3 Blink About this lesson: In this lesson, you will learn how to program your UNO R3 controller board to blink the Arduino’s built-in LED, and how to download programs by basic steps. Principle Fistly,you need to download and intall UNO The UNO R3 board has rows of connectors along both sides that are used to CH340G driver.
Page 35 You may find that your UNO R3 board's 'L' LED already blinks when you connect it to a USB plug. This is because the boards are generally shipped with the 'Blink' sketch pre-installed. In this lesson, we will reprogram the UNO R3 board with our own Blink sketch and then change the rate at which it blinks. In Lesson 0, you set up your Arduino IDE and made sure that you could find the right serial port for it to connect to your UNO R3 board.
Page 36 When the sketch window opens, enlarge it so that you can see the entire sketch in the window. 34/78...
Page 37 The example sketches included with the Arduino IDE are 'read-only'. That is, you can upload them to an UNO R3 board, but if you change them, you cannot save them as the same file. Since we are going to change this sketch, the first thing you need to do is save your own copy. From the File menu on the Arduino IDE, select 'Save As..' and then save the sketch with the name 'MyBlink'.
Page 38 You have saved your copy of 'Blink' in your sketchbook. This means that if you ever want to find it again, you can just open it using the File > Sketchbook menu option. 36/78...
Page 39 Attach your Arduino board to your computer with the USB cable and check that the 'Board Type' and 'Serial Port' are set correctly. 37/78...
Page 40 Note: The Board Type and Serial Port here are not necessarily the same as shown in picture. If you are using 2560, then you will have to choose Mega 2560 as the Board Type, other choices can be made in the same manner. And the Serial Port displayed for everyone is different, despite COM 26 chosen here, it could be COM3 or COM4 on your computer.
Page 41 Next, the status will change to 'Uploading'. At this point, the LEDs on the Arduino should start to flicker as the sketch is transferred. Finally, the staus will change to 'Done'. The other message tells us that the sketch is using 928 bytes of the 32,256 bytes available.After the 'Compiling Sketch..' stage you could get the following error message: 39/78...
Page 42 It can mean that your board is not connected at all, or the drivers have not been installed (if necessary) or that the wrong serial port is selected. If you encounter this, go back to Lesson 0 and check your installation. Once the upload has completed, the board should restart and start blinking.
Page 43 gle line comments start with // and everything up until the end of that line is considered a comment. The first line of code is: int led = 13; As the comment above it explains, this is giving a name to the pin that the LED is attached to. This is 13 on most Arduinos, including the UNO and Leonardo.
Page 44 You are now going to make your LED blink faster. As you might have guessed, the key to this lies in changing the parameter in () for the 'delay' command. This delay period is in milliseconds, so if you want the LED to blink twice as fast, change the value from 1000 to 500. This would then pause for half a second each delay rather than a whole second.

Page 56: Lesson 5 Servo
About this lesson: In this lesson, you will learn how to control a servo motor using LAFVIN UNO R3. The servo motor has three leads. The color of the leads varies between servo motors, but the red lead is always 5V and GND will either be brown.The red one is the power wire and should be connected to the 5v port and this is usually orange.
Page 57 Connection diagram 55/78...
Page 58 Code After connecting,please open the the program and load up the code - Lesson 5 Servo onto your Arduino board. See Lesson 3 for details about program uploading if there are any errors. Before you can run this, make sure that you have installed the < Servo> library or re-install it, if necessary. Otherwise, your code won't work.
Page 59: Lesson 6 Ultrasonic Sensor Module
Lesson 6 Ultrasonic Sensor Module About this lesson: Ultrasonic sensor is great for all kind of projects that need distance measurements, avoiding obstacles as examples. The HC-SR04 is inexpensive and easy to use since we will be using a Library specifically designed for these sensor. Introduction: Ultrasonic sensor module HC-SR04 provides 2cm-400cm non-contact measurement function, the ranging accuracy can reach to 3mm.
Page 60 range in proportion .You can calculate the range through the time interval between sending trigger signal and receiving echo signal. Formula: us / 58 = centimeters or us / 148 =inch; or: the range = high level time * velocity (340M/S) / 2; we suggest to use over 60ms measurement cycle, in order to prevent trigger signal to the echo signal.
Page 61 Wiring diagram 59/78...
Page 62 Code Using a Library designed for these sensors will make our code short and simple. We include the library at the beginning of our code, and then by using simple commands we can control the behavior of the sensor. After wiring, please open the program in the code folder- Lesson 6 Ultrasonic Sensor Module and click UPLOAD to upload the program. See Lesson 3 for details about program uploading if there are any errors.

Page 68: Lesson 8 L298N Motor Driver
Lesson 8 L298N Motor Driver About this lesson: In this lesson, you will learn how to use a L298N Motor Driver module. Component Introduction The L298N actually contains two complete H-Bridge circuits, so it is capable of driving a pair of DC motors. This makes it ideal for robotic projects, as most robots have either two or four powered wheels.
Page 69 Using L298N made by ST Company as the control chip, the module has characteristics of strong driving ability, low calorific value and strong anti-interference ability. This module can use built-in 78M05 for electric work via a driving power supply part. But to avoid the damage of the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage.
