First Up, I`m completely new to arduino and very sorry if my question sounds ridiculous, but I have a project I´m working on, that I think arduino would be perfect for (especially since I have an arduino nano since christmas
I would like to build an automatic filling machine for jam glasses, which is controlled by a balance. the filling would be done by a potentiostatically regulated extruder (that part is built and ready, so the arduino would only have to turn that one on and off)
So now to the problem/Question:
would it be possible to turn a relais on (and keep it on, for as long as a balance (one of those HX711 modules or similar) is above a certain value (empty container) and below another (targetet fill ammount plus empty container)
so the relais would have to have a vew functions
- tare the balance via switch
- display the current weight
- detect the empty glass weight and store it after pressing another button (maybe-5g so eventual variations are neglectable)
- be able to store the fill ammount (either via config from the pc, or even better via buttons on the system (can be in 1g or even bigger steps)
5 turn the power to the filling machine (12V DC motor) on and off
if that is too weird, It would also be fine for the machine to start dosing after the push of a button until the target weight is reached.
I hope I dont sound completely incoherent, and the idea is somewhat clear... I would greatly appreciate all inputs, cheers.
