Lesson Details

Lesson 1: Hello world

Introduction

For the first lesson, we will begin with something simple. This lesson is called "Hello World!". 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

EASY plug controller Board *1
USB cable *1

Sample Code

Connect the board to your PC using the USB cable; copy below code into Arduino IDE, and click upload to upload it to your board.

int val;// define variable val
void setup()
{
  Serial.begin(9600);// set the baud rate at 9600 to match the software settings. When connected to a specific device, (e.g. Bluetooth), the baud rate needs to be the same with it.
}
void loop()
{
  val=Serial.read();// read the instruction or character from PC to Arduino, and assign them to Val.
  if(val=='R')//  determine if the instruction or character received is “R”
  {  // if it’s “R”
   Serial.println("Hello World!");// display “Hello World!”
  }
}

Result

Open serial port monitor of the Arduino IDE, input “R”, click “Send”, you can see it displays “Hello World!”.

Lesson 2: Who's blinking

Introduction

After entry lesson of “Hello World!”, let’s up the stake and learn how to control the blinking of an LED. This lesson is quite simple. All you need to do is to connect an LED to one of the digital pins. We will be using hardware form "Hello World!" and also some extra parts.

Hardware required

EASY plug controller Board *1
EASY plug cable *1
USB cable *1
EASY plug Digital White LED Module *1

In the hardware list, you can see there is an EASY plug Digital White LED Module. Here is a brief introduction of it.

This LED module has a bright white color. It’s ideal for Arduino starters. You can easily connect it to the IO port of our EASY plug controller board. Its specifications are as below:

Type: Digital
PH2.54 socket
White LED module
Enables interaction with light-related works
Size: 33.7*20mm
Weight: 5g

Connection Diagram

Now, let’s connect this module to the D11 port of the controller board using the EASY plug cable, just as simple as that!

Sample Code

Connect the board to your PC using the USB cable; copy below code into Arduino IDE, and click upload to upload it to your board.

int ledPin = 11; // define digital pin 11
void setup()
{
pinMode(ledPin, OUTPUT);// define LED pin as output
}
void loop()
{
analogWrite(ledPin,255); //set the LED on, regulate light brightness, ranging from 0-255, 255 is the brightest
delay(1000); // wait for a second
digitalWrite(ledPin, LOW); // set the LED off
delay(1000); // wait for a second
}

Result

The LED will be on for one second, and then off for one second with an interval of one second, just like a shining eye blinking.

Lesson 3: Visible breath

Introduction

After the first two lessons, I believe you’ve grown familiar with Arduino. In this lesson, we will use the LED to do something else, simulating breath. Sounds cool? Well, let’s get on with it. We will still be using the same hardware form lesson 2.

Hardware required

EASY plug controller Board *1
EASY plug cable *1
USB cable *1
EASY plug Digital White LED Module *1

Connection Diagram

Now, connect the LED module to the D11 port of the controller board using the EASY plug cable.

Sample Code

Connect the board to your PC using the USB cable; copy below code into Arduino IDE, and click upload to upload it to your board.

int ledPin = 11; // define digital pin 11
void setup()
{
pinMode(ledPin, OUTPUT);// define LED pin as output
}
void loop()
{
for (int a=0; a<=255;a++)// set the LED to be brighter gradually 
{
analogWrite(ledPin,a); // turn on LED, regulate light brightness, ranging from 0-255, 255 is the brightest
delay(10); // wait for 0.01S
}
for (int a=255; a>=0;a--) // set LED to be dimming gradually
{
analogWrite(ledPin,a); // turn on LED, regulate light brightness, ranging from 0-255, 255 is the brightest
delay(10); // wait for 0.01S
}
delay(1000);// wait for 1S
}

Result

LED becomes brighter gradually, wait for 0.01S, then dimming gradually, wait for 1S, and then cycles on, just like the LED is breathing.

Lesson 4: Flowing light

Introduction

LED can do many things. I believe you have seen billboards with lights changing to form various patterns. Now, you can make one! This lesson is called Flowing light. We will need 2 more EASY plug cables and 2 more LEDs than the previous lesson.

Hardware required

EASY plug controller Board *1
EASY plug cable *3
USB cable *1
EASY plug Digital White LED Module *3

Connection Diagram

Now, connect the LED modules one by one to D9, D10 and D11 ports of the controller board using the EASY plug cables. LED becomes brighter gradually, wait for 0.01S, then dimming gradually, wait for 1S, and then cycles on, just like the LED is breathing.

Sample Code

Connect the board to your PC using the USB cable; copy below code into Arduino IDE, and click upload to upload it to your board.

int BASE = 9 ;  // the I/O pin for the first LED
int NUM = 3;   //  number of LEDs
void setup()
{
   for (int i = BASE; i < BASE + NUM; i ++) 
   {
     pinMode(i, OUTPUT);   // set I/O pins as output
   }
}

void loop()
{
   for (int i = BASE; i < BASE + NUM; i ++) 
   {
     digitalWrite(i, HIGH);    //set I/O pins as “high”, turn on LEDs one by one
     delay(200);        // wait 0.2S
   }
   for (int i = BASE; i < BASE + NUM; i ++) 
   {
     digitalWrite(i, HIGH);    // set I/O pins as “low”, turn off LEDs one by one
     delay(200);        // wait 0.2S
   }  
}

Result

3 LEDs turn on one by one, and then turn off one by one, just like flowing light.

Lesson 5: Make a sound

Introduction

After many light-related lessons, let’s learn how to make a sound. Sound experiment is usually done with a buzzer or a speaker, while buzzer is simpler and easier to use. In this lesson, we will learn how to make a sound with an active buzzer.

Hardware required

EASY plug controller Board *1
EASY plug cable *1
USB cable *1
EASY plug Active Buzzer Module *1

Here is a brief introduction of EASY plug Active Buzzer Module.

EASY plug Active Buzzer module is the simplest sound making module. It has an inner vibration source. Simply connect it with 5V power supply, it can buzz continuously. With Easy plug design, you can easily plug it into EASY plug controller board to have a try. Below are its specifications:

Working voltage: 3.3-5v
Interface type: digital
Size: 39*20mm
Weight: 6g

Connection Diagram

Now, connect the module to the D10 port of the controller board using the EASY plug cable.

Sample Code

Connect the board to your PC using the USB cable; copy below code into Arduino IDE, and click upload to upload it to your board.

int buzzPin =  10; // Connect Buzzer to D10
void setup()  
{        
 pinMode(buzzPin, OUTPUT);  // set I/O pin as “output” 
}
void loop()                    
{
 digitalWrite(buzzPin, HIGH);// set digital I/O output as “high”, the buzzer will sound
 delay(500);// wait for 0.5S
 digitalWrite(buzzPin, LOW);// set digital I/O output as “low”, the buzzer will stop making sound
 delay(500); // wait for 0.5S      
}

Result

The buzzer will ring for 0.5S and stop making sound for 0.5S.

Lesson 6: Who's singing

Introduction

In the previous lesson, we have learned how to make a sound. In this lesson, we will use another type of buzzer to code the melody of a song. It’s called a passive buzzer. Using the codes we gave you, this lesson is also quite simple.

Hardware required

EASY plug controller Board *1
EASY plug cable *1
USB cable *1
EASY plug Passive Buzzer module *1

Let’s first learn a little bit about this EASY plug passive Buzzer Module.

Different from active buzzer, passive buzzer is not set with a vibration source, so DC signal cannot make it buzz. A 2K~5K square wave is used to drive it. Different frequencies produce different sounds. So we can use Arduino to code the melody of a song. Below are its specifications:

Working voltage: 3.3-5v
Interface type: digital
Size: 39*20mm
Weight: 6g

Connection Diagram

Now, connect the module to the D8 port of the controller board using the EASY plug cable.

  1,1,1,1,
  1,1,1,0.5,0.5,
  1,1,1,1,
  1+0.5,0.5,1+1,
};
int length;
int tonepin=8;   // set module signal pin to D8 
void setup()
{
  pinMode(tonepin,OUTPUT);
  length=sizeof(tune)/sizeof(tune[0]);   // calculate length

}
void loop()
{
  for(int x=0;x<length;x++)
  {
    tone(tonepin,tune[x]);
    delay(500*durt[x]);   // this is use to adjust tempo delay, you can change the number to your liking.
    noTone(tonepin);
  }
  delay(2000);
}

Result

The buzzer will play Ode to Joy, and then pause for 2S.

Lesson 7: Temperature measuring

Introduction

In this lesson, we will learn how to measure the temperature of our surroundings. You may feel hot or cold sometimes, but how can you know for sure? Well, let’s measure it.

Hardware required

EASY plug controller Board *1
EASY plug cable *1
USB cable *1
EASY plug Analog Temperature Sensor *1

First, let’s take a look at this EASY plug Analog Temperature Sensor.

Analog Temperature Sensor is based on the working principle of a thermistor (resistance varies with temperature change in the environment). It can sense temperature change in its surrounding and send the data to the analog I/O in the controller board. Below are its specifications:

Interface type: analog
Working voltage: 5V
Temperature range: -55℃～315℃
Size: 38*20mm
Weight: 5g

Connection Diagram

Now, connect the module to the A1 port of the controller board using the EASY plug cable.

Sample Code

Connect the board to your PC using the USB cable; copy below code into Arduino IDE, and click upload to upload it to your board.

double Thermister(int RawADC) 
{
double Temp;
Temp = log(((10240000/RawADC) - 10000));
Temp = 1 / (0.001129148 + (0.000234125 + (0.0000000876741 * Temp * Temp ))* Temp );
Temp = Temp - 273.15; // Convert Kelvin to Celcius
return Temp;
}
void setup()
{
Serial.begin(9600);
} 
void loop() 
{
Serial.print(Thermister(analogRead(1))); // display Fahrenheit 
Serial.println(" c");
delay(500);
}

Result

Pic 1 is the temperature the sensor senses in serial monitor; pic 2 is when you blow air with your mouth to the sensor, the temperature goes higher; pic 3 is when you aim a fan to the sensor, the temperature drops. Now, you can know the exact temperature of your surroundings.

Lesson 8: Make a sound-controlled lamp

Introduction

This is a simple, but interesting lesson. We will make a sound-controlled lamp. Usually, this test is done by clapping your hand. But due to many sound interference in the environment, we will blow air into the sound sensor instead.

Hardware required

EASY plug controller Board *1
EASY plug cable *1
USB cable *1
EASY plug Digital White LED Module *1
EASY plug Analog Sound Sensor *1

First, let’s learn something about this EASY plug Analog Sound Sensor.

Analog Sound Sensor is typically used in detecting the loudness in ambient environment. The sound sensor can pick up sound signal and convert it into voltage value. You can use it to make some interesting interactive works such as a voice operated switch or a sound-controlled lamp in this lesson. Below are its specifications:

Supply Voltage: 3.3V to 5V
Detecting sound intensity
Interface: Analog
Size: 38*20mm
Weight: 6g

Connection Diagram

Now, connect the LED module to the D11 port of the controller board, and sound module to A0 using the EASY plug cables.

Sample Code

Connect the board to your PC using the USB cable; copy below code into Arduino IDE, and click upload to upload it to your board.

int ledpin=11;// set LED to D11
int soundpin=0;// set sensor to A0
void setup()
{
 Serial.begin(9600); // open serial port, set the baud rate at 9600 bps
 pinMode(ledpin,OUTPUT);// set LED pin as output
}
void loop()
{
 int val;
 val=analogRead(soundpin);   // read the value of sensor pin and assign it to val 
 Serial.println(val);
 if (val>170) 
  {            
  digitalWrite(ledpin, HIGH);  // turn LED ON
  } 
 else
  {
   digitalWrite(ledpin, LOW); // turn LED OFF
  }   
  delay(100);
}

Result

When you blow air into the sensor, the air vibrates; the sensor will pick up the sound signal and turn on LED.
