If you can't tell from the fact that this is my first post in 2014 and it's March already that I am not one for routine tasks, then I'll tell you. I'm not one for routine tasks. More often then not, I get distracted or forget. So when it comes to my water softener, I usually discover it's low after the black plastic spatulas all turn white. So it's about time I did something about it.
I was inspire by the cool (and cheap) HC-SR04 distance sensors. They look like cool little robot heads and can tell you how far away something is. I HAD to use one for something.
