(In advance I am EXTREMELY new to arduino and could use any help at all).
I am starting a new project with non-contact liquid level sensors and timers. The goal of the project is to have the arduino start and stop a timer based upon the liquid level in a large syringe.
For more detail, the liquid will start at the 100 mL mark. It will slowly decrease until it reaches the 60mL mark. At this point I would like the non-contact liquid level sensor to send a signal to the arduino and start a timer. Then, once the liquid hits the 30 mL mark, I would like another sensor to be able to turn off that timer and then display the result on an LCD display.
So my question is, what's the best way of going about this project with an arduino? I was considering using an UNO r3 but I am capable of getting any other type that may work better. Also, the non-contact liquid level sensors I had in mind can be seen with the following link:
Thank you in advance to any help at all!
