1. Introduction

Ardublock zero-based programming kit is a new graphical programming study kit which is based on Arduino enthusiasts and developed by keyestudio. It greatly lowers the difficulty in program learning for enthusiasts. All computer language and professional statements of a program can be simplified into blocks. Compiling is as easy as block building. Interactive with Arduino development board, they can achieve exciting works.

The open source feature of Arduino makes it extremely popular. You can find a many learning communities on the Internet. Ardublock is a graphical programming environment, just like blocks building, which greatly lowers the learning difficulty for starters. As long as you love it, everyone can play with Arduino without professional knowledge or relevant background.

Introduction

What’s Arduino? Arduino is an open-source hardware project platform. This platform includes a circuit board with simple I/O function and program development environment software. It can be used to develop interactive products. For example, it can read signals of multiple switches and sensors, and control light, servo motor and other various physical devices. It’s widely applied in robot field.


4. Arduino installation and program upload

5. Introduction of ArduBlock

Ardublock, developed by Shanghai Xinchejian, is a graphical programming environment software. ArduBlock is a third-party software of Arduino’s official programming environment. It can only work with Arduino software. Different from Arduino's text-based programming environment, it's in graphical form. Programming is like building blocks, which makes programming more visualized and interactive. It also greatly lowers the difficulties in programming. People with no programming experience can also compile a program for Arduino controller.

1. Installation Put “ardublock-beta-20140828”this file into the installing catalog of arduino IDE software, if no installing catalog, create one, for example, I put the file in D:\Program Files\Arduino\tools\ArduBlockTool\tool

Ardublock graphical programming environment offers a buzzer module. There are several parameters, including one buzzer connecting port, and the other one sound frequency.In this project, t1 is a variable to change the frequency of sound producing, which begins from 10, and increases 100 each time, up to 5000. Figure pin 13 is used as prompt, so when making a sound , LED blinks. “Dang”module is a cycle structure on condition that the value of t1 is less than 5000. When more than 5000, the cycle structure ends. Please have a try, to find in which frequency the sound is sweeter from 10 to 5000 in this mystical sound program.

Project 18: Reed Switch Module

Introduction:
The reed switch grass tube is full of highly purified inactive gas. Before operating, the two reeds are separated. Extra magnetic field produces different polarity around the endpoint of the two reeds, so that two different polar reeds attract each other and close.
In this project, we use graphical programming and regard reed switch module and magnet as a switch to control the on and off of LED.

Materials Required:
1. KEYESTUDIO UNO Control Board *1
2. V5 Sensor Shield*1
3. Piranha LED*1
4. Reed Switch Module*1
5. Female to Female Dupont Line*6

Project 19: Human Body IR Pyroelectricity

Introduction:
It is a human body detecting sensor based on infrared pyroelectricity, which can only detect moving body. That is to say, when you don’t move, it can do nothing. Still ,it is a digital sensor.
In this project, we use graphical programming and regard human body IR pyroelectricity and human body as a button to control the on and off of LED.

Materials Required:
1. KEYESTUDIO UNO Control Board *1
2. V5 Sensor Shield*1
3. Piranha LED*1
4. Human Body IR Pyroelectricity*1
5. Female to Female Dupont Line*6

  }
  else
  {
    Serial.print("No one!");
    Serial.println();
    digitalWrite( 6 , HIGH );
    delay( 1000 );
  }
}
*******************************************************************************

Result:
After the downloading is done, use reed switch module to check whether there is someone moving. If someone moving, piranha LED on and the serial monitor indicates “Somebody is in this area!”; if nobody moving, the LED off and the serial monitor indicates "No one!".

Project 20: Line Tracking Sensor

Introduction:
Line tracking sensor has a TCRT5000 photoelectric sensor. Infrared reflectivity of color is different ,which is applied to convert strong and weak echoed signal into current signal by photoelectric sensor. The potentiometer is used to adjust sensitivity of this sensor.
In this project, we use graphical programming to detect high and low level of line tracking sensor signal port and the color of objects, displaying it on serial monitor.

Materials Required:
1. KEYESTUDIO UNO Control Board *1
2. V5 Sensor Shield*1
3. Line Tracking Sensor*1
4. Female to Female Dupont Line*3

Project 21: MQ-2 Combustible Gas and Smoke Sensor

Introduction:
Arduino MQ-2 combustible gas sensor is mainly used to detect whether the gas leaks in industry and family. It can detect liquefied petroleum gas, methane, ethane, iso-butane, ethyl alcohol, hydrogen, smoke and ect. Potentiometer can be used to adjust the sensitivity of the sensor.
In this project, we use graphical programming to detect analog value of signal port of this sensor. When gases leak, the value increases and the LED is on .

Materials Required:
1. KEYESTUDIO UNO Control Board *1
2. V5 Sensor Shield*1
3. MQ-2 Combustible Gas and Smoke Sensor*1

After downloading program, you can use this sensor to detect whether the gas leaks. Open serial monitor, you can see the analog value of ambient gas. In this experiment, we detect the gas of a lighter. Open a lighter and close to the sensor after closing it, the analog increasing, and the red light on the sensor is on; the lighter away from this sensor, the analog value decreasing, the red light off.
