Simply program your arduino with the code on the Arduino folder
Make sure you have Python 3.5 and PyQT 5.6 installed, as well as pip install Pillow, PyAutoGui and PySerial.
This project is structured as a Python Package so instead of running python3 file.py you should, from the HES folder, run python3 -m Computer (or python -m Computer, if python 3 is your default python installation)
Note: The Computer/gui and Computer/driver folders are set up as packages themselves, so if you just want to test the GUI or the driver by itself you can run
python3 -m Computer.guiorpython3 -m Computer.driver
Using a Python Package allows us to use absolute imports instead of relative ones, which can be useful in many situations. You can read more about it here: https://docs.python.org/3/tutorial/modules.html#packages
