Arduino web interface boilerplate

This boilerplate lets you speak to an usb-connected arduino from your web browser.
This can be used to have a nice webapp that can handle arduino inputs/outputs.

I made this because existing examples were not simple, not auto-reloading, and not error-proof.

This boilerplate implements auto reconnection on both sides (server / client).

installation

server install

!!! This requires at least Python 3.5+ (see pymata_aio page)

pip install pymata-aio

arduino install

Open Arduino IDE and select File/Examples/Firmata/StandardFirmata. Connect your Arduino board to your computer, select the correct board type and port, and finally click the Upload button on the IDE.

usage

./run.sh

A web server is ran on http://localhost:3000.
You will be able to toggle the onboard arduino led from this page.

Interesting files are run.sh and index.html.
The pymata_iot.py is just here for convenience, it's simply copied from pymata_aio's repo.

Ctrl-C in terminal to shutoff everything.
You can F5 the page in your browser, it will auto-reconnect.

Stuff used to make this:

• Firmata for Arduino is an Arduino firmware that implements Firmata protocol
• pymata_aio is a Python asyncio client for the Firmata Protocol that supports websockets
