  I made more progress on the cat feeder tonight! ⁣
  ⁣I attached the motor to the back, and the shaft now goes thru and connects to the original (modified) plastic shaft from the dispenser.
  ⁣
  ⁣The lid has an ultrasonic distance sensor pointing down at the food to be able to tell how much is left in the chute.
  ⁣
  ⁣There's a button on top to be able to manually dispense a dose.
  ⁣
  ⁣Lastly, I added a terminal block to connect the wires from the scale for easier mounting to the processor later.
  ⁣
  ⁣Next up, I need to start connecting all the components to the circuitry! The load cell amplifier, stepper motor driver, and finally the esp32 controller. Then it'll be time to write some software!
