Studuino

151610Board speciﬁcation

Instructions● Studuino is a microcontroller board mounted with an AVR microcontroller, DC Motor drivers, and push-button switches aswell as Servomotor, DC Motor and sensor connectors.
● This single circuit board allows you to create programs that control Servomotors, DC Motors, and sensors.
● Studuino is an ideal resource for learning about programming, electronics, and robot creation.

It is necessary to install a USB device driver on your PC before
connecting Studuino to your PC USB port.

★ When installing the device driver, log in to your PC as an Administrator.
● Visit Artec's website at http://www.artec-kk.co.jp/en/studuino to download thedevice driver. Download PL2303̲Proliﬁc̲DriverInstaller̲v1.8.19.zip for Windows(XP, Vista, 7, 8) ormd̲PL2303̲MacOSX-10.6up̲v1.5.1.zip for Mac (OS X 10.6, 10.7, or 10.8).
Decompress the ﬁle and double click on the installer ﬁle to run it.
Follow the instructions as the installation program proceeds.
● For Windows Vista, 7, and 8 PCs with an Internet connection
Connect your Studuino to the USB port on your PC (Windows Vista, 7, 8).
A message will pop up, saying "Installing device driver software."
When the message "Your device is ready to use" appears, the software is installed.
★ During the process, UAC warnings may appear. If that happens, choose "Allow" andproceed with installation.

！ To program using Arduino IDE, the pre-loaded ﬁle in the
microcontroller needs to be overwritten.

Follow the process below.

LED light(1) Download boards.zip from http://www.artec-kk.co.jp/studuino and save it somewhere you
can ﬁnd it, such as your desktop. Decompress the zip ﬁle.
(2) Replace the boards.txt ﬁle in your Arduino folder with the ﬁle you have downloaded. Users withWindows PCs can ﬁnd it in \\arduino-1.0.x\hardware\arduino. Mac users will ﬁnd it in/Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/boards.txt.
(3) To edit the program using Arduino IDE, choose Studuino during the microcontroller selection
process.

Push-button switches

Shared with connectors A0, A1, A2, A3Caution● Use Arduino-1.0.1 and later to use Arduino IDE.
● The push-button switches on this board do not have pull-up resistors. Whenever you use
the push-button switches, conﬁgure the pull-up settings in the microcontroller.
Example) Code when using A0 push-button switch:pinMode(A0, INPUT̲PULLUP);● The maximum output current of the DC Motor driver IC is 1A.
● Refer to the following chart to see which DC Motor driver and microcontroller pins
correspond to each other.

D2, D3, and D4 cannot be used for other purposes while using DC Motor 1. Likewise, D5, D7, and D8

cannot be used when using DC Motor 2.

D2D7D4D3D8D5● When using commercially available shields with Servomotors or sensors at the same time,
use a pin socket between Studuino and the shield to make room for connectors.
● Choose which power supply to use by switching the on-board jumper. Select either 3.3Vor 5V (USB). Use 3.3V for regular operation.
● The external power supply should be inserted in the correct polarity. Failing to insert thepower supply correctly can damage the circuit board.
