Installing required Software

• To upload the code to the Arduino install Visual Studio Code. Inside Visual Studio Code install the Extention PlatformIO
• Open the project through the PlatformIO Homescreen. PlatformIO will download all required librarys to upload the code which are defined in the platformio.ini file automatically at the first upload
• Upload the code by clicking the upload/arrow button in the Toolbar
• Planning of the UI Layout is made with Figma
