Quickly get started with Pybricks

Create a new virtual environment, install the dependencies from requirements.txt, and open thefolder in VS Code.

python3 -m venv venv
source venv/bin/activate  # On Windows use `venv\Scripts\activate`
pip install -r requirements.txt

Robot Blink Script

This repository includes a simple MicroPython script for Pybricks hubs:

robot_blink.py - Robot Face Animation

A script that prints "Hello World" and displays a blinking robot face using Matrix patterns on the LED display. The robot has sensors, eyes, and features that create a friendly animated face with periodic blinking.

.vscode/launch.json - VS Code Debug Configuration

A sample configuration for debugging Pybricks scripts directly from VS Code using the pybricksdev tool.

How to Run

  • F5 to start debugging in VS Code (ensure that you updated the launch.json with your hub name)
  • In terminal: pybricksdev run ble robot_blink.py -n "John"
  • Or run via USB connection: pybricksdev run usb robot_blink.py

Expected Behavior

  • Console prints "Hello World!" and animation status messages
  • LED matrix displays a robot face with sensors, eyes, and features
  • Eyes blink periodically (closed eyes are dimmer)
  • Pattern loops continuously with "Blink!" messages until stopped

Compatible Hubs

  • LEGO SPIKE Prime Hub
  • Not tested on other hubs but should work with minor adjustments

Note

  • Make sure your hub is powered on and connected before running the scripts.
  • Check the Pybricks documentation for more information on supported features and limitations.
  • When using Bluetooth, the Spike Prime Hub should be blinking blue to indicate it is in pairing mode.

The import errors shown in VS Code are normal - these scripts are designed to run on the MicroPython environment on the Pybricks hub, not in your local Python environment.
