Prerequisite
Install Arduino IDE
The Arduino software IDE Integrated Development Environment (IDE) allows you to write
programs and upload them to your board.
Here, you will learn how to set up the software to
program your board.
Step 1: Go to the Arduino download page: https://www.arduino.cc/en/Main/Software shown
in Figure 1.
The version available from official website is the latest version, the figures in this tutorial might
be slightly different from yours.
Select one Arduino IDE according to your operating system download. (Take Windows as an
example) There are two versions of Arduino for Windows: Installer and
ZIP file. Click “Windows
Installer”.
Figure 1 Arduino IDE Download Page
Step 2: Press the button “JUST DOWNLOAD” to download the software shown in Figure 2.
Figure 2 Download

10
Step 3: Double click the "windows.exe" file to the following dialog box and then click "I Agree"
and then click "Next".
Step 4: Click "Browse" to choose the installation path or enter a directory at the Destination
Folder. Click "Install" to initiate installation.
Step 5: After installation ended, click "Close" to finish.

11
Step 6: When the dialog box pop us like Figure 2 shown, Select Always trust software for
"Adafruit Industries" and click "Install".
Step 7: When the installation is done, click "Close". Then an Arduino icon will appear on the
desktop:

Add Libraries and Open Serial Monitor
Add Libraries
Libraries are a collection of code that makes it easy for you to connect to a sensor, display,
module, etc. For example, the built-in LiquidCrystal library makes it easy to talk to character
LCD displays. Libraries provide extra functionality for use in sketches, e.g. working with
hardware or manipulating data. There are hundreds of additional libraries available on the
Internet for download. To use the additional libraries, you will need to install them.
To install the library, first exit the Arduino IDE. Then unzip the ZIP file of the library (download
from the GitHub link). Copy the library file into your libraries folder (This PC\ Documents\
Arduino\ libraries\). Next, restart the Arduino IDE, you will find the library appears in the
Sketch->include library shown in Figure 3.
There may be more files excluding the .cpp and .h files in the library folder, 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.
Figure 3 Include library

13
Compile and download program.
Click the tools to select the correct board and the port you're using as shown in figure 4 and
figure 5.
Figure 4 Select Board
Figure 5 Select Port
Click the verify icon to compile and make sure your program is correct and then click the
upload icon to download the program shown in Figure 6 and Figure 7.
Figure 6 Verify sketch Figure 7 Download sketch
Open Serial Monitor
The Serial Monitor is a separate pop-up window that acts as a separate terminal that

14
communicates by receiving and sending serial data. The serial monitor is the 'tether' between
the computer and your UNO. It lets you send and receive text messages, handy for debugging
and also controlling the UNO from a keyboard. See the icon on the upper right of Figure 8. You
just need to click the serial monitor icon to open it.
Figure 8 Serial monitor
To send data to the board, enter text and click on the "send" button or press enter. Choose the
baud rate from the drop-down that matches the rate passed to Serial.begin in your sketch.
Which port selected to open in the serial monitor is the same as the port for uploading Arduino
code. Go to Tools -> Serial Port, and select the correct port.
How to start a lesson
Step 1 Add the library (This step only needs to do once, if you have already installed, please
skip this step.)
Step 2 Find and double click the file of lesson code, then you will see the IDE dialog box.
Step 3 Connect the components according to the connection schematic and wiring diagram.
Then connect your UNO board or MEGA2560 to PC via the USB cable.
Step 4 Compile and download the program. Then you will see the result.

Lessons
Lesson 1 Blink and Breathing LED
Overview
In this project, you will learn the simplest thing you can do with an Arduino and see physical
world by blinking the on-board LED and without doing any programming.
Second step, you will learn how to use the PWM square-wave signal to control the external
LED as a breathing lamp which gradually becomes brighter and then gradually becomes dark.

Component Introduction
The UNO R3 board has rows of connectors along both sides that are used to connect to
different electronic devices and plug-in 'shields' that extends its capability.
It also has a single LED that you can control from your sketches. This LED is built onto the
UNO R3 board and is often referred to as the 'L' LED as this is how it is labeled on the board.
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.
Since the first experiment of blinking onboard LED is quite so easy without any programming,
it just gives you an idea about how electronic device works. The next step we will try something
interesting and more complex by connecting a breadboard and external LED to build a
breathing lamp.
Breadboard is just a grid of holes in a plastic block. Inside are
strips of metal that provide electrical connection between holes
in the shorter rows. Pushing the legs of two different
components into the same row joins them together electrically.
LED is the abbreviation of light emitting diode. The LED has two electrodes, a positive
electrode and a negative electrode, it will light only when a forward current passes. Generally,
the drive current for LED is 5-20mA. Therefore, it needs an extra resistor for current limitation

16
to protect the LED. Otherwise, it will burn out!
In the following connection schematic, you will see the picture shown "+" "-"
In the wiring diagram, the longer pin (the curved pin) represents anode, the opposite one is
cathode.

In the first step experiment we blink the onboard LED by tuning it on and off, the brightness of
LED can't be changed. So in the second step we will use PWM technique to adjust the brightness.
Pulse Width Modulation, or PWM, is a technique for getting analog results with digital means.
Digital control is used to create a square wave, a signal switched between on and off. This on-off
pattern can simulate voltages in between full on (5 Volts) and off (0 Volts) by changing the portion
of the time the signal spends on versus the time that the signal spends off. The duration of "on
time" is called the pulse width. To get varying analog values, you change, or modulate, that pulse
width. If you repeat this on-off pattern fast enough with an LED for example, the result is as if the
signal is a steady voltage between 0 and 5v controlling the brightness of the LED.
In the diagram below, the green lines represent regular time period. This duration or period is
the inverse of the PWM frequency. In other words, with Arduino's PWM frequency at about 500Hz,
the green lines would measure 2 milliseconds each. A call to analog Write () is on a scale of 0 - 255,
such that analog Write (255) requests a 100% duty cycle (always on), and analog Write (127) is a
50% duty cycle (on half the time) for example.

Lesson 2 LED Flowing Lights
Overview
In this lesson, you will master how to use eight large red LEDs with an UNO or MEGA2560
board without using up 8 output pins.

74HC595 IC 1 Breadboard 1
Component Introduction
The 74HC595 is an 8-stage serial shift register with a storage register
and 3-state outputs. Each of which can either be a 1 or a 0. The shift
register and storage register have separate clocks. To set each of
these values on or off, we feed in the data using the pin 'Data' and 'Clock' of the chip.
The clock pin is used to receive eight pulses. At each pulse, if the pin "data" is high, then a 1
gets pushed into the shift register; otherwise, a 0.
When all eight pulses have been received, enabling the pin of "Latch" copies those eight values
to the latch register. This is necessary; otherwise, the wrong LEDs would flicker as the data is
being loaded into the shift register.
The chip also has an output enable pin (OE), which is used to enable or disable the outputs
all at once. You could attach this to a PWM-capable pin of UNO and use 'analog Write' to

Component Introduction
The switch is a simple component. When you press a button or flip a lever, they
connect two contacts together so that electricity can flow through them.
Actually, there are only really two electrical connections. Inside the switch
package, pins B and C are connected together as same as pins A and D.
