Good point. The delay setup is just for controlling the pumps. Once we add complexity, I will change accordingly later. Any thoughts on pros-cons of just using millis() (for those who don't know, it records the time since the device was turned on). I know it resets after a few days, but if I'm just concerned with dt (time differences), would it matter?Originally Posted by Mr. Ninja
I really like the idea of using a Pi, but how well do the two interface? Would you write the code for an arduino sketch or just have it connected to the Pi and write the code through that?
