Voor een schoolproject probeer ik een gps-module te laten werken met mijn arduino pro micro. Ik heb echter geen verstand van coderen en ik heb een voorbeeldcode van internet gebruikt. Deze code geeft echter de foutmelding dat in deze regel: Serial.print(byteGPS, BYTE); bij void loop het keyword BYTE niet langer wordt ondersteund. Hoe kan ik de code omschrijven zodat de module wel werkt?
/*
Listen for the $GPRMC string and extract the GPS location data from this.
Display the result in the Arduino's serial monitor.
