Alright, i made a program that is like a parking, when one car comes, presses on a button and it revervs a parking place(it changes a led from green to red). My program has 3 places you can park. I want do make a mobile app so that you can rezerve a spot and also show you what places are already parked and how many available.
What program can i use so i can make this . I know how to program in python.
