I finally added the potentiometer functionality, i also added the function that checks all pins, i also added a settings page where you can wipe the whole config, edit the wifi setting, change the credentials and can change the timzone. I lastly added a few small things like wifi reconnecting, mDns and a option to choose between common anode and common cathode. It is nearly finished, i only want to improve the security a bit, clean up the code and add some popups for things like having changed the config
