Week 12 - Machine Making

This week, we made a drink mixing machine! Definitely a gauntlet. I specifically worked on:

  • The Cuttlefish hunk for the drink mixer (with Alexandre and Premila)
  • The microcontroller hunk for the moduleboard (with Premila)
  • The circuits (with Hannah and Premila

Cuttlefish Hunk

Basically you pick a drink from the list, hit the button, and it will output a location to the stepper motor (via Saturn) and then the corresponding pump (via the MC hunk we wrote).

It also outputs to the console what it's up to.

And here's the logic behind it:

Microcontroller Hunk

This FSM explains how the hunk we loaded onto the module works:
