Install the required Python packages if not done already (some packages might already be installed):
sudo apt update
sudo apt install python3-socketio
sudo apt install python3-engineio
sudo apt install python3-flask-socketio
sudo apt install python3-flask-cors
Go to /webserver in a terminal window, run the flask server:
export FLASK_APP=build.py
export FLASK_DEBUG=1
flask run
Go to /pi in another terminal window, run the Pi controller:
python3 pi_controller.py
In the terminal running pi_controller.py, use the keys 'wasd' to move the 'drone' on the website.
Note: Don't use python3 build.py to run the webserver, since this does not porvide all the functionalities required by the application.
