It's not multithreaded... that's why I wrote "Arduino multithreading"... search for it and read then you'll know what I'm talking about
Ah, ok... then 1-2 times a second would be sufficient... Still the power of one Ardu is more than enough to do a lot more than just what it does here... try and you'll see... Just add some timings and don't do everything on each loop, but just when it's neccessary ("multithreading", timers, interrupts - use those, or even a simple loop counter will do wonders in this project).
Except there's no hard work to be done here. There's just too much updates in a small time frame.Time - can be updated just once a minute.LCD - can be updated just as needed (e.g.every minute after time changes or after user interaction)Sensor - since it monitors the sun can be read at 1-5 min intervals and that will be sufficient.And this is done in the main loop without any timings from what I've seen (haven't go through the entire code) - so we can safely assume that those things are done at least dozens (or even hundreds) of times per second.
Try optimizing the code a bit.Maybe some "Arduino multithreading"?And from what I've seen I think you should start by not updating the time on each loop.This really isn't too much for a single Arduino.
Ok.Think of it that way... A simple 16MHz ATmega can drive a CNC machine on it's own (like 3D printer etc). And that uses some owesome math procedures and floating point operations (which take a lot of time for those CPUs, since they don't have a FPU).Based on that a small duino shouldn't break a sweat with your code.Also alongside the time updates the LCD updates take a long time - this also can be done e.g. once a second or even less often.
