Sensors output is 0-190 ohms (2 wire output). Output needs to activate 4 (empty -- -- full) red LEDs sequentially as the tank fills. What component will activate as a SW by 0, 63, 126, 190 ohms? And how to wire the four SWs from a two wire input. Source 12v. Thanks for looking

I want manage my water tank. Do you have any idea how can I do that ??? If you have any idea about sensor I can use, would be great.

@vomaxa said in Best 3d printers:

What‘s a good, semi-affordable, good, maybe upgradeable, good 3D printer? I read a comparison article between a number of printers, and the one they liked the best was the Prusa. Which of course I had never heard of, and isn‘t sold on Amazon. Creality seems like the most popular on Amazon. It does not have to come from. Amazon, I just shop there a lot.

I have no experience at all with 3D printers, but I was an IT tech for years, have done a fair amount of coding and played with Raspberry Pi a bit. I want something I can learn on, but not so limited I would want to replace it within 3 months.

thanks in advance for any help
