"""Step 2 - Find the robot car.

This script only looks. It does not move the car.

Run it:
    Windows:  python find.py
    Mac:      python3 find.py

Install bleak first:
    Windows:  python -m pip install bleak
    Mac:      python3 -m pip install bleak

On a Mac, say yes when it asks for Bluetooth.
If you miss it: System Settings > Privacy and Security >
Bluetooth > turn on your Terminal app.
