Description

Coding Tool Kit < RTI ID = 0.0 >

The present invention relates to a coding tool kit, and more particularly, it relates to a coding tool kit, in which a fixed mounting board using only specific sensors used in coding training or physical computing education is removed, (Sensors, buttons, tact switches, sensors) and output devices (motor, LED, LCD, buzzer, speaker) and other parts. Input devices, output devices, and other components are detachably attached to the coding tool kit, can be configured and extended using jumper cables, and can be extended with block-type program tools such as scratches and entry sensor boards A text-coding programming tool of the type can be used, and most tools capable of supporting an arduino board can be used, (Bluetooth) for wireless data transmission and reception with a smart phone, and to use IoT (object Internet) using wireless communication, ) And a coding tool kit that provides a programmable kit that is as modular as possible in order to emphasize programming training rather than circuit training.

Physical Computing is a method of transferring a digital signal from a user in a physical way by inputting information, passing visual information through a screen, moving out of a method such as a keyboard input or a mouse click, So that the computer reacts according to the role of the human senses.

Dan O'Sullivan and Tom Lgoe, authors of Physical Computing, categorized the physical forms of physical computing into four categories, dividing the physical input and physical output into digital and analog, respectively.

1) Digital input

When a work reads information about the outside world in digital form 0 and 1. It is typical to read whether the switch is connected or disconnected. This is the case, for example, if there is a person in front of the work, or if the light is on or off in the room.

2) Digital output

If the work controls the external device in digital form of 0 and 1, it means that the external device is turned on or off. These include turning the LED on and off, making the buzzer sound or not, and not pulling or pulling on the solenoid.

3) Analog input

If your work reads information about the outside world in analog form, then there are several projects that use sensors. For example, the amount of weight of a person in front of the work, and how bright the lighting in the room is.

4) Analog output

This means that when a workpiece controls an external device in an analog form, that is, it does not simply turn on and off an external device, but also controls the strength and direction of the output. Brightness control of LED, height control of buzzer sound, and angle control of servo motor.

<Formal Physical Education Formats - Focused on Arduino> -

Physical computing, an area of software education, requires complex circuit configurations. In order to understand complex circuits as shown in the picture above, knowledge of sensors, basic knowledge of voltage, current, resistance, etc., and ability to understand circuit diagram are accompanied. In the end, the field of physical computing for students is made up of elements that are going to be very difficult.

After learning that it is this circuit configuration, full-fledged coding education is going to be difficult, because the most important purpose of software education is that it requires too much prior knowledge to know in advance of programming problem-solving ability education. Therefore, most of the physical computing education has been focused on robot education.

Although physical computing education is becoming more active in solving these problems little by little, there are still many problems to be solved. Hereinafter, the tools for teaching physical computing are (1) an entry sensor board, (2) a board for S Junior Software Academy, and (3) a pico board.

(1) Entry sensor board

1.1 Functions of the Entry Sensor Board

2 is a photograph of the entry sensor board.

Educational physical computing tool installed on an arduino board (can not be used without an arduino board). Program with a block programming tool called 'entry'.

The entry sensor board can program the ability to turn the LED bulb on and off.

The entry sensor board can be programmed to respond to the ability to click a button (switch).

The entry sensor board can be programmed to respond to ambient sounds using a sound sensor.

The entry sensor board can be programmed to take advantage of slide sensors (variable resistors).

The entry sensor board can be programmed to respond to ambient light intensity using a light sensor.

The entry sensor board can be programmed with the ability to measure temperature using a temperature sensor.

Thus, the entry sensor board can understand the concept of physical computing relatively easily and can be utilized for programming.

1.2. Disadvantages of entry sensor board

The sensor is fixed to a small size such as a credit card.

It is inevitable that a complicated process such as a circuit must be formed on the breadboard in order to use sensors other than the fixed sensor.

The entry sensor board encapsulates the programmable ports due to the fixed sensors attached to it, which may cause interference to other sensors that must use the port. The sensors that are unnecessary for actual work are always attached.

In the case of software education, physical computing is important in terms of maker education and creativity education that produce something on its own, but it is hard to use realistically except fixed sensors, and even if it is possible to use it, It can not be avoided. You have to learn how to handle a single device, and there are limitations that you must program within the framework of the functionality provided by the device.

(2) board for Junior Software Academy of S Electronics

2.1 Features of Board for Junior Software Academy

Figure 3 is a photograph of a board for Junior Software Academy of S Electronics.

S Electronics' board for Junior Software Academy has no specific designation but it is a board developed for software education (physical computing, coding education) in S Electronics.

S Electronics' board for Junior Software Academy is a physical computing teaching board that can be used with open source scratch developed by MIT, an educational programming tool. Since the board has its own firmware already mounted in the microcontroller (MCU), it does not need an additional IDUNO like an entry sensor board.

The board can be programmed to respond to the ability to click a button (switch).

The board can be programmed to respond to ambient sounds using a sound sensor.

The board can be programmed to utilize a slide sensor (variable resistance).

The board can be programmed to respond to ambient light quantities using a light sensor.

The board can be programmed to measure temperature using a temperature sensor.

The board can additionally be equipped with a resistance sensor, and simple sensors of the type using a resistance can be additionally used.

2.2 Disadvantages of Board for Junior Software Academy

Since it is based on the old version of Scratch V1.6, there is a limit to already use unless upgrading the firmware from S electron. At present, scratch has been upgraded to V2.0 or higher, so education utilization is falling.

The board for Junior Software Academy can not be improved without professional knowledge because it uses the firmware uploaded at the production stage, not the form that the user uploads the firmware like the entry sensor board.

The board for junior software academy is similar in function to the entry sensor board due to its fixed sensors, and it can recognize and program data values using sensors, but it does not have the function of outputting LED. In other words, there is no INPUT function, but no OUTPUT function (except for turning on the LEDs on the entry sensor board, the OUTPUT actuator function is not expected before the additional circuit configuration).

The board for the Junior Software Academy has the same disadvantages as the fixed sensors attached to the entry sensor board.

(3) Pico board

4 is a photograph of pico-boards.

PicoBoard is not the same as the board for Junior Software Academy of S Electronic. These are the prototype or basic models of sensor boards.

(4) Other boards

Figure 5 is a photograph of the other boards.

It can be applied to school students for educational purposes with kits (Kits) made in the form of an integrated board with a large amount of integrated sensors that can be mounted on an arduino board. However, They are. It is not a form that can be utilized except for the purpose of practicing the functions of the sensors. In addition, it can not escape from the concept of fixed attachment sensor and it is difficult to use it for the purpose of teaching physical computing and coding education. Also, it is difficult or difficult to extend the components beyond those attached to the board. In addition, there is a problem that a separate circuit must be formed even if the board is further expanded.

In recent years, the need for coded education in middle and high school students in the 5th and 6th grades has led to the introduction of curriculum in the name of software education with the addition of educational elements such as computer science (CS), computer thinking (computing sinking, Is beginning to enter.

Currently, the transition period is a form in which the school secures its own time to encourage education, but the curriculum will be compulsory in the middle school from 2017. Elementary schools will replace computer and robot-related units with software training in the 5th and 6th grades from 2018.

In particular, physical computing must be included in middle school and above, and physical education is encouraged in elementary school by using discretionary activities and after-school activities. Therefore, in order to implement physical computing education, it became necessary to develop more educationally appropriate tools and boards.

2) Concept of coding toolkit

① In Arduino education, solve difficulties of circuit configuration and pin connection so that you can concentrate on programming.

② It breaks the boredom of coding education to look only at the computer monitor screen, and executes the game by using various input / output devices of the practice kit instead of mouse and keyboard.

③ Practice kit can be practiced in both directions because there are both input device and output device. In other words, you can view the results of programming on a computer in a hands-on kit (eg flashing LEDs) or manipulate a computer game in a practice kit (eg, moving a volume to break bricks)

④ By using fixed pin position, it is possible to control all I / O devices by one programming. In other words, even if a touch sensor or an infrared sensor is inserted in place of the volume switch, the game can be controlled directly without any programming modification.

⑤ It is easy to add various input and output devices by detachment method and learn various features and functions at once (additional sensors are provided as an extended set pack).

⑥ The module size considering the development stage of the students and the structure that can be easily stored are adopted.

⑦ Designed products based on long research and field experience in alternate computer education specialists and coded education teacher groups.

* A basic set of coding tool kits.

A-1 code: A board equipped with a microcontroller for controlling input and output, a control board having a power supply connected to a USB connector, a case, and a power adapter, for example: Aduno main body (Aduno, cable, case, Power adapter)

C-1 code: Communication part (Bluetooth, RF433Hz, xBee, RFID, NFC etc ...)

O-1 code: Output (Output related motor, LED, LCD, buzzer, speaker ...)

I code: The I (Input) code consists of a button, a tact switch, an input

   - I-A1: Among the I codes, the A (Analog)

   - I-D1: Among the I codes, D (Digital)

E Code: Other Parts

A basic set of coding tool kits is provided as follows.

A-1. Arduino UNO R3

The main MPU chip of the coding toolkit's control board uses the same ATmega328 chip (microcontroller) as all products (genuine, domestic, and Chinese). Instead of this difference, you can use a communication chip to control UART communication (serial communication interface) of PC USB and Arduino board.

A-2. Arduino UNO CASE

Considering the cost of mold making and the method of separately manufacturing the Aduno Uno case from the development company, there are many types of Abu Noono cases sold on the market, but transparent acrylic is used. However, the buyer must assemble using screws.

A-3. USB cable

Purchase A to B type. On the market, the genuine Arduino Uno board has a USB port type B. By the way, there are a lot of Arduino that comes out of the micro USB port in line with the trend of using smart phones these days. Therefore, a USB cable of 1 ~ 2m length is used so that it can be connected to PC desk, coding tool kit and control board according to the USB port of the Adunono board to be purchased.

A-4. Power adapter

Coding tool kit power adapter can be DC 5 ~ 20V, but DC 7 ~ 12V is recommended. An adapter rated at 1A-1.5A at the output of DC 9V is most suitable.

C-1. Bluetooth

In the embodiment, the Bluetooth of the coding tool kit recommends the HC-06 model. It is produced in large quantities and is very affordable and goes well with Android smartphones. The original module of HC-06 is for 3.3V. However, the Arduino board is operated at 5V DC. To avoid this inconvenience, the HC-06 is usually attached to the backboard and is often fabricated to be DC 3.3V-5V.

O-1. Servo Motor

Servo motor with 0-180 ° swivel angle makes the SG90 comfortable and inexpensive.

However, this servo motor only operates about one self-voltage and current of the board. Personally, it was often operated only by the power supply of the PC via USB, but in a place such as a computer room, the USB power of the PC supplied to the Aduno Uno board was low and it often did not work. Ultimately, an external power supply is required. Larger motors should, of course, supply external power using a power adapter.

O-2. Infinite rotation servomotor

An infinite rotation servo motor (360 ° continuous rotation servo motor) is also included in the expansion set.

O-3. DC Gear Motor

To properly utilize the DC gear motor, you need to add a motor driver.

If you are configuring a basic set of coding tool kits, implement only a simple speed adjustment function using diodes and transistors (not reversible). When selecting a motor, a low voltage, low current small micromotor is needed considering the block specification.

O-6. Vibration motor

The vibration motor uses a coin type with a coin shape of about 10-20 pie. It is usually used for 3.3V. It is safe to attach diodes and transistors for safety against reverse current generation. The vibration motor is configured in an extension set.

O-7. LED (Red)

O-8. LED (Green)

O-9. LED (Yellow)

O-10. LED (Blue)

O-11. LED (White)

Please refer to the datasheet as the voltage of 5mm LED differs according to manufacturer and color.

For example, Red LED, Green LED, and Yellow LED have a resistance of about 180 Ω, and White and Blue LED have a resistance of about 130 Ω. And, although it was processed a little cleaner by using LED holder, it is neat when it is not necessary to use the holder when making mold.

-Voltage: 1.8-2.2V (Basic Red, Green, Yellow)

-Voltage: 2.4-2.7V (White, Blue)

-Max current: 20mA

-Suggested using current: 16-18mA

Because it is used for educational purposes, it is easy to consider large LED of 10mm size.

O-12. laser

The laser requires a resistor (R) and is included in the extension set. Although the laser output is a weak product, safety precautions are required, since laser parts may display safety warnings, as they may affect visual acuity of students.

O-13. Buzzer

The buzzer has a passive model and the active model. The passive model does not sound by power supply alone, but it only works when pulse (frequency) is generated. The active model sounds easier with just the power supply, which is easier for elementary school students. Therefore, we use the active model.

O-14. speaker

The speaker exhibits almost the same behavior as the buzzer. Speakers have a higher quality sound than buzzers, but they are configured in an extension set to save money. A buzzer is suitable for 8Ω 0.5W, and a diameter of about 20-25 psi is suitable.

O-15. CLCD

1602 Use the CLCD model to display simple alphabets, letters and numbers. Character LCD (CCLD) will use a lot of pins of Arduino. It uses a backpack module that converts it to I2C method.

O-16. CLCD BackPack (PCF8574)

Allows multiple pins of the CLCD to use only two I2C pins. In the Uno of Arduino, I2C pins are A4, A5 pins.

I-A1. Infrared proximity sensor (TCRT5000)

It can be used for line tracing and analog signal output. 100Ω is required for the transmitter LED and 10KΩ for the receiver (pull-down resistor connection)

I-A2. Optical Sensors (CdS)

A resistance of about 10 kΩ is required. Students should have a large sensor area (pull-down resistor connected) for use.

I-A3. Temperature sensor (thermistor)

I usually use a lot of thermistors about 10KΩ. In addition, a resistance of about 10 kΩ is required (a pull-down resistor is connected).

I-A4. Potentiometer

Potentiometers are variable resistors that convert linear and rotational displacements into changes in electrical resistance. They are contact type and non-contact type. The contact type is a structure in which the brush moves in the resistance position. In the linear type, the stroke is about 1,000 mm. In the case of the rotary type, there is one rotation to many (multi) rotation. Include in the default set.

I-A5. Hall Effect Sensor

The Hall Effect is used to check whether the magnet is present or not, and to check the opening and closing of the doors, or to check the rotation of bicycle wheels. Similar to the usage of the lead sensor, the Hall effect sensor is configured in the extension set.

The Hall effect sensor is divided into a digital zero and one representation, an analog representation of magnitude of the magnet, and a ratchet sensor.

I-A6. Rain sensor

The rain sensor is a sensor that detects rain or water and can measure high and low water levels. Because it is a relatively interesting sensor for students, it is organized into a basic set to increase interest.

I-A7. Flame sensor

It is a sensor that detects flame. It is highly utilized in laboratory practice, but elementary school students may construct flame for testing purposefully. Flame sensor products are marked with danger statements to prevent accidents.

I-A8. Moisture sensor

The moisture sensor measures the degree of moisture in the soil. It is a highly interesting sensor that is often used for pollen management.

I-A9. Temperature sensor (LM35)

The temperature sensor is a sensor that measures an ordinary temperature of about 0 ° C to 100 ° C with an error range of 0.5 ° C. Similarly, the TMP36 temperature sensor can measure up to 50 ° C, but it is twice as expensive as the LM35 temperature sensor.

I-A10. Acceleration Sensor (ADXL335)

Most acceleration sensors, gyros, compass, and pressure sensors are somewhat difficult sensors for elementary school students because they use SPI and I2C ports. The ADXL335 Acceleration Sensor is very simple to use because the x, y, and z axis values are output as analog signals (10 bits). However, pins are used simultaneously with three analog pins. Configure it in the extension set.

I-D1. Temperature and humidity sensor (DHT11, DHT22)

These sensors are configured in the expansion set, as two temperature sensors are already covered. It is good because it can measure humidity, but elementary school students have a hard time to handle and use it for middle and high school students.

I-D2. Tilt

SW-200d, and SW-520d are referred to as tilt sensors, but the tilt sensor is not a tilt sensor, but a digital switch that distinguishes whether the tilt sensor is simply tilted or erected.

I-D3. Tact Switch

Used for button input and for basic set, extension set or breadboard.

I-D4. Reed sensor

The lead sensor is a sensor that measures the presence or absence of a magnet. The lead sensor is slightly different from the Hall effect sensor. The Hall effect sensor can express to the nearest extent of the magnet, but this simply expresses the presence of the magnet as 0, 1.

I-D5. Waterproof type temperature sensor (DS18B20)

Liquid temperature measurement is possible and is suitable for scientific laboratory equipment of laboratory. For elementary students, it is somewhat difficult to deal with, so they are organized into extension sets.
