Introducing CODEino2

CODEIno2 board is a new type of single board microcontroller that combines Arduino and scratch sensor board, and is a Korean Arduino board for coding education officially adopted in 4 types of middle school ICT class textbooks.

CODEIno2 is an Arduino compatible board, equipped with all functions of Arduino, as well as Light, Sound, Button, Slider and 3-axis acceleration sensors on the scratch sensor board as standard, and having 4 analog input ports, you can easily input the value of an external sensor through a simple alligator clip cable connection.

In addition, it is possible to switch between the Arduino and the scratch sensor board with a simple switch control, so that you can proceed step-by-step learning with one board without purchasing an Arduino and scratch sensor board separately.

CODEIno2 is used not only for basic coding education, but also for various making activities by using CODEIno2 boards in regular Middle school courses, school club activities, after-school schools, and software-oriented universities.

Name of each part of CODEino2 and settings

Through the setting of the deep switch and 2 slide switches, CODEino2 can switch to the Arduino mode or Scratch sensor board mode.

• Arduino Mode

After cutting off the link the specific analog (digital) pin and sensor connection by a switch, and then change by the Arduino port; this mode enables to connect the jumper wire or Dupont wire cable to external products or module. At that moment if all the switches are set up at Arduino mode, you can use the CODEino2 and the Arduino Uno under the same conditions, most of the Arduino Uno compatible shield and module can be used so it extends the functions of CODEino2.

• Scratch Sensor Board mode

This mode enables to use easily the relevant sensor even if a specific circuit is not made up with a switch connecting a specific analog (digital) pin with the sensor inside a CODEino2. The scratch sensor mode depending on the slide switch 1 and 2 is separated into to 2 modes: the “S” mode and the “G” mode. The “S” mode, can read out the external resistance and sensor value by using the external analog input port (resistance A, B, C, D) external which uses the alligator clip cable.

The “G” mode uses the sensor of 3 AXIS acceleration and reads out the value of the acceleration of 3 AXIS sensor Y and Z.

The CODEino2 board is listed in Korea's four secondary textbooks.

The CODEino2 board in the textbook is a regular coding education tool used in elementary, middle, high school and university in Korea.
