Otto Blockly

This is a free and open source visual programming language based on Blockly from Google & MIT, to generate C/C++ code, compile and upload to multiple options of microcontrollers. Compatible with any Otto DIY robot, Arduino or ESP8266 and ESP32 related boards. It is the perfect software to get you started into coding and STEM robotics.

Installer

This software can work offline (standalone) by installing it on your computer. Depending on your operating system the installation files are already available or you have to create them yourself.

Windows and MacOS

Download the installer from the releases page. After the software is installed in your PC, it is ready to use immediately, you do not need to import Arduino libraries or any additional setup for the boards because it comes with a copy of the Arduino CLI, it is all in one software!, you will be ready to upload codes directly to your robot or any other Arduino project via USB.

If your computer do not recognize the USB device or Otto, you have to install the CH340 or CH341 or FTDI driver that is in the "driversUSB" folder or download from this link

Linux

For Linux operating systems go to this repo.

How to Use

1. Open any example.
2. Connect your Otto robot.
3. Select your board and the USB port where Otto is connected.
4. Upload and yes is that easy you can even just click upload and the code will be automatically compiled!

Drag, drop, connect, mix, play and create your own codes. Join the Otto Builder community, see all the cool stuff we are making with Otto Blockly and post your ideas!

Help us add new Languages

Leave your mark in the world by translating Blockly, you are welcome to contribute with any languages you know, it will benefit you and everyone in your community.

The more people helping to translate the better, it is important to translate while understanding the context and what is the robot actually doing to be accurate.

1. Go to the lang folder and duplicate the Arduino_en.js Blockly_en.js and msg_en.js files from English
2. Rename them according to your ISO language code, for example fr is for French, so the files are renamed like this: Arduino_fr.js Blockly_fr.js and msg_fr.js
3. Edit the files with any code editor software like Visual Studio Code translating only the English part after = in between the quotes "" in visual studio is the text in red.
4. Then open a pull request here in github or just attach the files in a new issue.

How to run project

You will need to have installed the node.js tools in your computer. The version must be the 12.0

1. Clone or download the source code.

git clone https://github.com/OttoDIY/blockly.git

2. OPEN GIT BASH as Administrator and cd in folder

cd blockly

3. Install required tools.

npm install -g build-tools npm install -g windows-build-tool (this command is not working ok. If the log is held then you must install python 2.7 before because the problem is with the python installation.) npm install -g node-gyp

4. Install required node modules. Execute following on the source code directory

npm install

5. Install Arduino CLI get arduino-cli.exe from https://github.com/arduino/arduino-cli/releases and place it under compilation/arduino

cd compilation/arduino curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh mv bin/arduino-cli ./ rm -rf bin

6. Execute following to install required tools

cd compilation\arduino arduino-cli core update-index arduino-cli core install arduino:[email protected] arduino-cli core install arduino:[email protected] arduino-cli core install arduino:[email protected] arduino-cli core install esp8266:[email protected] arduino-cli core install esp32:[email protected] arduino-cli core update-index

7. Build (creates .exe and .zip) You can use electron-builder to pack your electron app in zip, nsis (Installer), portable (App without installation) formats.

cd ../../ # ( go back to the repository’s top directory) npm run compiler or build --win --ia32 export PATH=$PATH:node_modules/.bin npm install [email protected] build --mac --x64 electron-builder --mac --x64

How to Contribute
