1. Introduction

1.1. Setup

Before beginning, visit http://www.artec-kk.co.jp/en/studuino and download the

document Studuino Programming Environment Setup for reference.

1.2. Connecting Parts

① Connecting sensors, Buzzers, and LEDs

Sensor connecting cables are used to link sensors to the Studuino board. The

cables attach to Sensor/LED/Buzzer connectors located on the board, as shown below.

★ The three-wire cable is used for every sensor except the accelerometer, which requires a four-wire cable.

★ Sound, light, and reflective infrared sensors connect to A0 through A7.

★ Touch Sensors, LEDs, and Buzzers connect to A0 through A5.

★ Accelerometers connect to both A4 and A5.

★ Push-button switches A0-A3 cannot be used when using a sensor with connectors A0-A3.

Sensor/LED/Buzzer connectors

Gray wires face inside as shown.

② Connecting a DC Motor

Up to two DC motors can be connected using connectors M1 and M2.

★ DC motor cables can only fit into the connector one way.

★ DC motor connector M1 cannot be used at the same time as servomotor connectors D2 and D4.


③ Connecting a Servomotor

Up to eight servomotors can be connected to the servomotor connectors.

④ Connecting a Battery Box

Connect the battery box cable to the POWER pins.

Sensors/LEDs/Buzzers/switches can use voltage supplied via USB, but DC motors

and servomotors require voltage from the power jack. When USB is disconnected,

all devices require voltage from the power jack to operate.

③ Drag three blocks to the Script field and stick them together. Set

them to be 0, 12, and 15, as shown below.

④ Click and the blocks connected to will be executed in order. The

values 0, 12, and 15 will appear in the list.

The following steps will explain the processes of the list you made in step 4.

⑤ Next, delete the blocks created in step 3. After that, attach to

A new second row with a

value of 30 will be

inserted into the list

24

⑨ Next, delete . Drag to the Script field.

Attach it and set it to delete the value in the second row of list_note.

⑩ Click .

You can use the steps listed above to modify (add, insert, substitute, or delete)

values in a list. You can also access the information in the list with the following blocks.

Block Process

● Playing a Melody using a List

The program created in 3.4. Playing a Melody runs seven times with different

pitches using combined blocks. We’ll simplify this program by using a list to set the pitch

of the block.

⑪ Delete and then delete all the list elements.

⑫ Drag seven blocks and stick them together as shown.

Drag and drop Make each element

active by clicking on it. Then click the x

that appears

26

⑬ Enter the values below into the blocks.

These values will be used for the pitch.

⑭ Drag from the Control palette and stick it to the top of the blocks

created in step 13. Click on the ▼ then choose "new..." and give the function the

name "init_code."

The completed "init_code" function will set the pitch of each note of "Twinkle,

Twinkle, Little Star." Blocks attached to will be executed when the

program runs. When is executed, each will run and the

numbers will be added to the list.

③ Name it "init_code."

㉑ Connect a block from the Control palette and set it to 7.

The program you’ve just completed uses a list to play the beginning of Twinkle,

Twinkle, Little Star, performing the following actions.

The value of "number" increases by 1 every time a loop completes, using "number"

as a variable to play each sound registered to the list in order.

Connect your Studuino to the PC via USB and choose Transfer from the Run menu.

The Buzzer will play Twinkle, Twinkle, Little Star once the program transfers.

Repeat 7 times

Set variable "number" to 1

Studuino board to PC via USB cable. Choose Test ON from the Run menu.

⑧ When in the Test mode, click .

Do not disconnect the USB cable during Test mode.

Blocks being used by the program are shown with a white frame. Check if the LED

flashes by shading the light sensor with your hand to make it darker.

From the menu, select Run and then Transfer so that the program is transferred to

the Studuino board. It can now be run using battery power instead of a USB connection

to your PC.

The program will be run in

the Sensor Board appears and shows "[A2] Touch Sensor."

The Touch Sensor sends a value of 1 in its normal state, and 0 when touched.

Press the Touch Sensor and check if values of the Sensor Board window respond.

4.4.4. Programming

Now we'll use the Touch Sensor to create a program that makes an LED flash

when the Touch Sensor is pressed and learn to create a program using .

① From the Motion palette, drag and attach to . Set to

the LED to OFF.

② From the Control palette, drag and attach to .

57

③ From the Operators, drag and attach as shown.

④ Drag from the Sensing palette and attach it to the left side of

. Set 0 for the right side value.

⑤ Drag from the Control palette and attach it to the other blocks.

Now the program is finished. It will make an LED flash two times when the

Touch Sensor is pressed.

Connect your Studuino board to PC via USB cable. Choose Transfer from the Run

menu. Check if the LED flashes when the Touch Sensor is pressed.

Turn off the LED

Wait until the button is pressed

4.5. Sound Sensors

Sound Sensors measure the loudness of a sound.

4.5.1. Connecting a Sound Sensor to the Studuino Board

Connect a Sound Sensor to Sensor/LED/Buzzer connector A3 on the Studuino

board.


Set the port information in the Block Programming Environment to match your


open the setting dialog box. In the Port Settings dialog box, uncheck A3 in the Button

area and check A3 in the Sensor/LED/Buzzer area and select Touch Sensor. Check A4

and select LED.

4.5.3. Checking the Sound Sensor

Now we're going to find the value of the Sound Sensor. Connect your Studuino

board to your PC via USB cable. Choose Test ON from the Run menu. In Test mode,

the Sensor Board appears and shows [A3] Sound Sensor.

The Sound Sensor value represents the volume of a sound using numbers from

0 to 50. Silence returns a value of 0, and increases as the sound becomes louder. Try

blowing on the Sound Sensor or making other sounds and to see if the values change in

the Sensor Board.



4.5.4. Programming

Now we're going to use the Sound Sensor to make a program that turns a

blinking LED off if you blow on the Sound Sensor using the block.

① From the Motion palette, drag to the Script field.

The values should change depending

on how loud a sound you make

61

② From the Control palette, drag and attach to the block in step 1.


④ Connect the duplicated blocks to the originals.

The blocks will be

duplicated

① Right click

⑥ From the Control palette, drag to the Script field.

63

⑦ From the Operators palette, drag and attach as shown.

⑧ From the Sensing palette, drag and attach to the left side of

. Set 30 for the right side value.

⑨ Move the blocks made in step 4 to the opening in .

64

This program will make a blinking LED turn off if you blow on the Sound Sensor

(if the value becomes greater than 15).

⑩ Attach the blocks made in step 8 to .

⑪ From the Motion palette, drag and attach . Set to the LED to OFF.

65

Now we've made a program that will make a blinking LED turn off if you blow on

the Sound Sensor.

⑫ Check to see if the LED turns off if you blow on the Sound Sensor. Connect your


⑬ When in the Test mode, click .


Blow on the Sound Sensor and check if the LED turns off if the value of the

Sound Sensor becomes greater than 15.

From the menu, select Run then Transfer so that the program is transferred to

the Studuino board and then it can be run using battery power instead of a USB

connection to your PC.

The program will be run in

Test mode
