  • add LCD screen for serial messages
  • make cup weighting bulletproof, stop if wait decreases significantly before pouring finished
  • dancing bottles should dance also in reverse direction
  • Problem: orig might be measured if there is no cup
  • Problem: when cup is away, bottle pours directly to scale and causes weight
  • Error handling? (scale?)
  • when cup is not there while pouring, abort pouring procedure (check if weight gets less between bottles)
  • empty bottle error handling
  • MAX_DRINK_SIZE implement!
  • rename UPRIGHT_OFFSET --> STOP_EARLY_GRAMS <-- won't fix
  • auto calibration for UPRIGHT_OFFSET
  • Serial commands for different speed?
  • move bottle according to non-linear predefined function
  • Serial command: calibrate scale, SET_OFFSET (tare)
  • WON’T FIX Serial command: all to pos_up, all down
  • abort button
  • resume button
  • buttons for predefined drinks
  • abort command
  • pause/command switch
  • do we check the number of params?
  • move bottles at the same time?
  • Protothreads?
  • fix Makefile for Arduino One
  • serial reconnect --> reset arduino?
  • problems with pin 13
  • READY: add 0/1 if cup or not
  • UPRIGHT_OFFSET / 2.0 (if less, don't do anything if more pour)
  • dancing bottles!
  • improve dancing bottles by turning more bottles at the same time
  • store some stuff in EPROM (eg. scale calibration, etc.)
  • Serial command: calibrate scale, not only tare
  • dancing bottles should move backwards as well

Testing: - empty bottle - cup away: between pouring, before, after - max drink size - scale timeout - invalid commands
