Stap 4: Python code op PC
Op de PC zal ik python gebruiken om te ontvangen van de opdrachten van de arduino en vertalen naar sleutel-persen.
Op uw PC moet u Installeer python 2.7, de win32-bibliotheek en de pySerial bibliotheek.
Recieve.pyw
Ik ben met behulp van de .pyw-extensie, zodat het draait op de achtergrond.

In dit bestand waarvan u de naam wilt wijzigen van de "button" array aan alle de gewenste knoppen. Nadat u dat hebt gedaan hoeft je alleen het uitvoeren van dit script.
! Let op!
Bij het indrukken van een toets die u moet drukken korte, anders itll ' voeren dezelfde opdracht voor de naam van de volgende sleutel.
