How to Use

1. Running the Remote Server

To use the remote backend (for cloud or remote Jupyter/Colab environments), you need to run the remote server on the machine connected to your Arduino hardware.

Install dependencies:

pip install -r .\requirements.txt

Run the server: RUN server with default settings (localhost):

python -m arduino_colab_kernel.backends.remote_server

OR use custom port and token:

python -m arduino_colab_kernel.backends.remote_server --port 5000 --token YOUR_TOKEN

• Replace YOUR_TOKEN with a secure token of your choice.
• The server will listen for requests from the frontend (Colab/Jupyter).

1.1 Open server site in web-browser

Open server URL address in web-browser and copy TOKEN, and Server URL if needed.

2. Connecting from the Client (Colab/Jupyter)

In your Jupyter/Colab notebook, load the magics and set up the remote backend:

%load_ext arduino_colab_kernel.magic_project
%load_ext arduino_colab_kernel.magic_board
%load_ext arduino_colab_kernel.magic_code
%load_ext arduino_colab_kernel.magic_serial

MY_API_TOKEN = input("Enter your API token: ")  # Use the same token as the server
REMOTE_URL = "http://<server-ip>:<server-port>"  # Replace <server-ip> and <server-port> with your server's IP address and port (*Optional*)

# Load or initialize a project in remote mode
%project load --mode remote --remote_url $REMOTE_URL --token $MY_API_TOKEN
# init
%project init --mode remote --remote_url $REMOTE_URL --token $MY_API_TOKEN

# or use simplify version with default server address:
%project load --mode remote --token {MY_API_TOKEN}
# init
%project init --mode remote --token {MY_API_TOKEN}

3. Workflow

• Use %project, %board, %%code, and %serial magics as usual.
• All compile/upload/serial operations will be forwarded to the remote server.

Example

# Set up remote backend
MY_API_TOKEN = "YOUR_TOKEN"
REMOTE_URL = "http://192.168.1.100:5000"

%project init my_project --mode remote --remote_url $REMOTE_URL --token $MY_API_TOKEN
%board select uno
%%code setup
pinMode(13, OUTPUT);
%%code loop
digitalWrite(13, HIGH); delay(500); digitalWrite(13, LOW); delay(500);
%board upload
%serial listen --duration 10

Security

• Always use a strong, secret token for authentication.
• Never expose your remote server to the public internet without proper security.
