So i am making a dispensing machine with a peristaltic pump. The problem with peristaltic pumps are that they need to be calibrated, usually involving a precision scale, were one would measure the weight of the fluid (this is common practice in laboratories etc.)
I have found a peristaltic pump with a stepper, but i can’t find any precision scales for arduino. Do you know were to get one? One that could send the measurement over serial would be preferable, because i don’t think that the arduino’s 1024 bit resolution for analog read will give me the precision i need, although i might be wrong here, so suggestions here are also welcome.
Other ideas for pumps that can dispense a precise amount of liquid are welcome as well. The liquid have charcoal in it, so it does contain small lumps (no problem for a peristaltic pump!).
