Steg 2 av projektet: 

Nästa steg är att få arduino att göra något när GPS:en byter värde, T.ex att tända en lampa. I koden nedan så är det inställt så att när värdet av Latitude MIN1 är = 13 så tänds lampan. Att använda en lampa var bara ett exempel, man kan fast få den att spela ett ljud eller något annat, fantasin sätter gränserna. Här slutar jag med mitt projekt men arbeta gärna vidare på det själv!IMG_20180523_091654.jpg
