Introduction
As for starters, we will begin with something simple. In this project, you only need an Arduino and a USB cable to start the “Hello World!” experiment. This is a communication test of your Arduino and PC, also a primer project for you to have your first try of the Arduino world!
Hardware Required
1.V4.0 Board *1
2.USB Cable *1
Sample Program
After installing driver for Arduino, let’s open Arduino software and compile code that enables Arduino to print “Hello World!” under your instruction. Of course, you can compile code for Arduino to continuously echo “Hello World!” without instruction. A simple If () statement will do the instruction trick. With the onboard LED connected to pin 13, we can instruct the LED to blink first when Arduino gets an instruction and then print “Hello World!”.
Result
Click serial port monitor,Input R,LED 13 will blink once,PC will receive information from Arduino: Hello World
After you choosing the right port，the experiment should be easy for you!
Project 2：LED blinking
Introduction
Blinking LED experiment is quite simple. In the “Hello World!” program, we have come across LED. This time, we are going to connect an LED to one of the digital pins rather than using LED13, which is soldered to the board. Except an Arduino and an USB cable, we will need extra parts as below.

Circuit Connection
Sample Program
According to the above circuit, you can start compiling the program, turning the LED 1 second on and 1 second off. This program is simple and similar to one that comes with Arduino except it’s connected to digital pin 10.

After downloading this program, in the experiment, you will see the LED connected to pin 10 turning on and off, with an interval approximately one second.
The blinking LED experiment is now completed.
Project 3: Traffic Light
Introduction
In the previous program, we have done the LED blinking experiment with one LED. Now, it’s time to up the stakes and do a bit more complicated experiment-traffic lights.

Since it is a simulation of traffic lights, the blinking time of each LED should be the same with those in traffic lights system. In this program, we use Arduino delay () function to control delay time, which is much simpler than C language.
Result
When the uploading process is completed, we can see traffic lights of our own design.
Note: this circuit design is very similar with the one in LED chase effect.
The blue light will be on for 5 seconds, and then off., followed by the yellow light blinking for 3 times, and then the red light on for 5 seconds, forming a cycle. Cycle then repeats.

Arduino IDE is based on C language, so statements of C language such as while, switch etc. can certainly be used for Arduino program.
When we press the button, pin 5 will output high level. We can program pin 10 to output high level and turn on the LED. When pin 5 outputs low level, pin 10 also outputs low level and the LED remains off.

When the button is pressed, LED is on, otherwise, LED remains off. After the above process, the button controlled LED experiment is completed. The simple principle of this experiment is widely used in a variety of circuit and electric appliances. You can easily come across it in your every day life. One typical example is when you press a certain key of your phone, the backlight will be on.

Project 10: Analog Value Reading
Introduction
In this experiment, we will begin the learning of analog I/O interfaces. On an Arduino, there are 6 analog interfaces numbered from 0 to 5. These 6 interfaces can also be used as digital ones numbered as 14-19. After a brief introduction, let’s begin our project. Potentiometer used here is a typical output component of analog value that is familiar to us.
Hardware Required

5. Breadboard Jumper Wires* Several
Circuit Connection
In this experiment, we will convert the resistance value of the potentiometer to analog ones and display it on the screen. This is an application we need to master well for our future experiments.
Connection circuit as below:
We use the analog interface 0.
The analog interface we use here is interface 0.
Sample Program
The program compiling is simple. An analogRead () Statement can read the value of the interface. The A/D acquisition of Arduino 328 is in 10 bits, so the value it reads is among 0 to 1023. One difficulty in this project is to display the value on the screen, which is actually easy to learn. First, we need to set the baud rate in voidsetup (). Displaying the value is a communication between Arduino and PC, so the baud rate of the Arduino should match the the one in the PC’s software set up. Otherwise, the display will be messy codes or no display at all. In the lower right corner of the Arduino software monitor window, there is a button for baud rate set up. The set up here needs to match the one in the program. The statement in the program is Serial.begin(); enclosed is the baud rate value, followed by statement for displaying. You can either use Serial.print() or Serial.println() statement.
Result
The Sample Program uses the built-in LED connected to pin 13. Each time the device reads a value, the LED blinks.
Below is the analog value it reads.
When you rotate the potentiometer knob, you can see the displayed value changes. The reading of analog value is a very common function since most sensors output analog value. After calculation, we can have the corresponding value we need.
The experiment is now completed, thank you.
Project 11: Photo Resistor
Introduction
After completing all the previous experiments, we acquired some basic understanding and knowledge about Arduino application. We have learned digital input and output, analog input and PWM. Now, we can begin the learning of sensors applications.
Photo resistor (Photovaristor) is a resistor whose resistance varies according to different incident light strength. It’s made based on the photoelectric effect of semiconductor. If the incident light is intense, its resistance reduces; if the incident light is weak, the resistance increases. Photovaristor is commonly applied in the measurement of light, light control and photovoltaic conversion (convert the change of light into the change of electricity).
Photo resistor is also being widely applied to various light control circuit, such as light control and adjustment, optical switches etc.
We will start with a relatively simple experiment regarding photovaristor application. Photovaristor is an element that changes its resistance as light strenth changes. So we will need to read the analog values. We can refer to the PWM experiment, replacing the potentiometer with photovaristor. When there is change in light strength, there will be corresponding change on the LED.

Circuit Connection
Connecting buzzer:
Connect the controller board, prototype board, breadboard and USB cable according to the Arduino tutorial. Connect the buzzer to digital pin 8.
2）Connecting flame sensor:
Connect the sensor to analog pin 0.
Experiment Principle
When it’s approaching a fire, the voltage value the analog port reads differs. If you use a multimeter, you can know when there is no fire approaching, the voltage it reads is around 0.3V; when there is fire approaching, the voltage it reads is around 1.0V, tthe nearer the fire, the higher the voltage. So in the beginning of the program, you can initialize voltage value i (no fire value); Then, continuously read the analog voltage value j and obtain difference value k=j-i; compare k with 0.6V (123 in binary) to determine whether or not there is a fire approaching; if yes, the buzzer will buzz.
Sample Program
Result
This program can simulate an alarm when there is a fire. Everything is normal when there is no fire; when there is, the alarm will be set off immediately.
Project 13: Analog Temperature (Thermistor)

Project 19: 1-digit LED Segment Display
Introduction
LED segment displays are common for displaying numerical information. It’s widely applied on displays of electromagnetic oven, full automatic washing machine, water temperature display, electronic clock etc. It is necessary that we learn how it works.
LED segment display is a semiconductor light-emitting device. Its basic unit is a light-emitting diode (LED). LED segment display can be divided into 7-segment display and 8-segment display according to the number of segments. 8-segment display has one more LED unit ( for decimal point display) than 7-segment one. In this experiment, we use a 8-segment display. According to the wiring method of LED units, LED segment displays can be divided into display with common anode and display with common cathode. Common anode display refers to the one that combine all the anodes of LED units into one common anode (COM).
For the common anode display, connect the common anode (COM) to +5V. When the cathode level of a certain segment is low, the segment is on; when the cathode level of a certain segment is high, the segment is off. For the common cathode display, connect the common cathode (COM) to GND. When the anode level of a certain segment is high, the segment is on; when the anode level of a certain segment is low, the segment is off.
Common cathode 7-segment display
Common anode 7-segment display
Each segment of the display consists of an LED. So when you use it, you also need use a current-limiting resistor. Otherwise, LED will be burnt out. In this experiment, we use a common cathode display. As we mentioned above, for common cathode display, connect the common cathode (COM) to GND. When the anode level of a certain segment is high, the segment is on; when the anode level of a certain segment is low, the segment is off.
Hardware Required
1. V4.0 Board *1
2. USB Cable *1
3. 1-digit Segment Display*1
4. 220Ω Resistor *8
5. Breadboard*1
6. Breadboard Jumper Wires* Several
Circuit Connection
Sample Program
There are seven segments for numerical display, one for decimal point display. Corresponding segments will be turned on when displaying certain numbers. For example, when displaying number 1, b and c segments will be turned on. We compile a subprogram for each number, and compile the main program to display one number every 2 seconds, cycling display number 0 ~ 9. The displaying time for each number is subject to the delay time, the longer the delay time, the longer the displaying time.
Result
LED segment display displays number 0 to 9.
