The current situation: the Router and Server is in the center of the house and the speed is slow on either side of the house. The router is a regular little TP-link Router + modem 4G.

So I have an arduino uno, motor controller, pump, and an RTC DS3231 (idk if its needed).
I want the pump to pump for like 5 seconds every other day from t=0, every 48h.
i have some coding experience but have no idea how to code. So where do I even begin here. Do I just use delay(999999999999999); or is there a more effiecent way of doing it?
Verkar som det gör det ändå

I haven't tried a shoe without a tounge before so I'm not sure about that.
I need a shoe that works in 10C to 25C and in blazing sun heat. Should be able to handle some rain.
Also have you felt a difference between a black colored shoe and a lighter colored shoe in how hot they get?
