Nothing is in place. It will be an experimental project where I can use the principles learned to help me with something in the future.
I would rather work with a syringe pump or peristaltic pump so that the liquid lines stay isolated. Also a weight sensor or perhaps some sort of light sensor/reflective rather than conductance detection in the liquid would be better
Flow rate does not have to be fast, just enough to top up 300ml or something.
Can anyone recommend any specific components/shields that I can buy? What sort of power or boards do I need to run the motors on the pumps? Will I have enough space to run a feedback loop on the sensors on one board?
