2. Set the CALLIOPE_PORT value in the plot_ecg.py file to match your device's location.
3. Run the App (will auto-install any dependencies): pixi run python plot_ecg.py
4. Use the scroll button on the mouse to zoom in and out, and drag the white threshold line in "Filtered Heartbeat Signal" to just below the maximum point where a heartbeat signal happens!
