Python

Please note, if you already have Python installed and know how to use it, you do not need to read this. This is a beginners guide to installing Python only

Python is a high-level programming language used for scripting, automation, and backend tooling.

For Makerthon26, Python is used to run a local WebSocket bridge that connects:

Your Arduino (via USB Serial)
Your browser app (Lovable) via WebSocket

The bridge simply translates messages between hardware and the web app.

Setting up Python

This guide is for Windows users.

We recommend installing Python using PowerShell so that it is automatically added to your system PATH.

Step 1 – Open Powershell (PowerShell Method)

Note: You must be connected to the internet. If any issues, contact us for help.

Press Win + X
Click Windows Terminal* / **Terminal / PowerShell

Press Terminal

Step 2 – Search for Python installs using `winget` command:

- Run `winget search Python.Python`
- You should see a list of available python versions to download

Search Python Downloads

Step 3 - Install a Python version

We’re installing Python v3.12
Run winget install --exact --id Python.Python.3.12 (Note: the --exact and --id just makes sure there is no name conflicts)
When prompted, type Y to accept conditions
Python will be installed succesfully and PATH variable updated automatically.

Python Install Command

Step 4 - Verify installation

Close PowerShell first (we have to relaunch the terminal because it needs to refresh PATH Variables)
Reopen PowerShell according to step 1
Run the command python --version
It should output “3.12.10” or something similar

Check python installed

Step 5 - Install dependencies for this Makerthon

Run pip install websockets pyserial
It should install websocket and pyserial libraries
