BlocklyDuino is a web-based visual programming editor for Arduino.

BlocklyDuino is based on Blockly, the web-based, graphical programming editor. Provide static type language blocks and code generators for Arduino programming.

BlocklyDuino also support Grove blocks to easily get started with microcontroller-based experimentation and learning.

• Programming Arduino with visually drag and drop code blocks
• Generate fully compatible Arduino source code
• Interactive Arduino board with 10+ predefined Grove sensor blocks
• Load different on-site examples with url parameters
• Theme choice

BlocklyDuino is a web tool. You can give it a try at Web to see the working BlocklyDuino.

You can link directly to examples

• demo 1 make default LED blink
• demo 2 control servo with potentio rotator
• demo 3 click button to change LED colors

If you want to install it locally. Get code from github and open blocklyduino/index.html in your browser.

The preffered way is to put the BlocklyDuino/web folder into a web server and open the url like localhost/public/blocklyduino/index.html for use.

To avoid the tedious step of manually pasting code to the Arduino IDE, you can run a mini webserver that uses the Arduino IDE to upload the code to a connected Arduino board on Windows, Mac OS X and Linux systems. Invoke this command from the BlocklyDuino root folder:

python arduino_web_server.py

You can optionally specify the port with --port=COM3 (or --port=/dev/tty.foo on Linux and Mac); if you don't, it will try and guess which port to use.

When the webserver is running, you can access BlocklyDuino itself on http://127.0.0.1:8080/.

1. Open browser to BlocklyDuino, drag and drop blocks to make an Arduino program
2. Select the 'Arduino' tab and copy all of the source code into an existing or new project in the Arduino IDE
3. Press the 'Upload' button in the Arduino IDE to burn the code into a connected Arduino board

OR (if running ino_web_server.py):

1. Open browser to BlocklyDuino, drag and drop blocks to make an Arduino program.
2. Select the 'Arduino' tab and press the 'Upload' button. (press the 'Reset' button to upload an empty program)

Thanks Neil Fraser, Q.Neutron from Blockly https://developers.google.com/blockly/ Thanks Dale Low (gumbypp) for contribute the python server to pipe BlocklyDuino source to arduino board. Thanks Arduino and Seeeduino guys for Arduino and Grove blocks.

The project is also inspired by arduiblock and modkit
