### 5/5 — 쉽게 코딩하고 무선 제어가 가능한...

*2019-05-02*

아두이노는 너무 어렵게 느껴져서 구입하고도 잘 다루지 않고 있는데, 엘리오는 쉽게 코딩하고 무선으로 제어하여 작동시킬 수 있어 아이들이 매우 좋아하네요.

학교에서 실습재료로 사용 중인데, 연결이 쉽고, 다른 부품들도 시중에서 쉽게 구매가 가능하여 다양하게 활용하고 있습니다.^^

집에서는 블럭으로 조립하고 엘리오를 붙여 작동시키니 아이들도 매우 좋아합니다.^^

다소 아쉬운점은 9볼트 건전지의 가격이 만만치 않다는 점인데, 이걸 충전지로 대체하려 고민중입니다.

## Version history (last 5 releases)

### 1.32 — 2025-03-28

Create new model data files for controlling Mecanum Wheel cars

### 1.31 — 2024-07-26

There was an error related to the LED ON/OFF function in the Blockly coding blocks, which I have urgently fixed.

### 1.30 — 2024-06-08

I hope this message finds you well. I am currently engaged in teaching primary and secondary school students using Elio boards and ESP32 boards. As part of the curriculum, it is necessary for the students to communicate with an HTTP server running on the ESP32 board through the Elio app.

Due to the memory constraints of the ESP32 board, we are unable to implement an HTTPS server, and thus we rely on HTTP communication. Given that this program is solely for educational purposes, I kindly request that you grant us the permission to use HTTP communication by including the necessary permissions in the info.list.

Your consideration in approving this request would greatly enhance the learning experience of the students by allowing them to understand and interact with web server functionalities in a practical environment.

Thank you very much for your attention and support.

### 1.29 — 2024-06-07

Issue:
We encountered an internal error when driving the motor. Specifically, the motor only recognized the positive direction while generating an error in the negative direction.

Fix:
The error has been corrected to ensure proper motor operation in both positive and negative directions.

### 1.28 — 2024-02-06

"Fixed an internal error that was causing frequent disconnections with Bluetooth devices."
