WIO Terminal based cocktail mixing robot
Untested as of now. (still building the hardware)
Delivers a signal to relais or mosfets to drive up to 11 (or more, if you adjust the code) peristaltic pumps - up to 3 are active at the same time (Can be adjusted in Code, depends on the current your power source can deliver). The flow is monitored for empty-bottle or other fail-detection (untested in practice) by a load cell with a HX711. Also the presence of a Cup is detected with the load cell. Also the content of each flask is estimated (but nothing happens with this info yet).
flask-names, flowcalibrationdata, scale calibration and recipes are read from customizable txt files on an SD-card at startup.
Leaves space for unknown ingredients in the recipes - good for filling up a premix with the main ingredient as the peristaltic pumps can be slow. cocktail-size can be adjusted at runtime.
