who needs access to A10? We can only do it Tue night during class hours.
bookstore has not shipped yet. we will get tracking #’s when they do.
This is in the kit: ELEGOO UNO Project Super Starter Kit with Tutorial and UNO R3 Compatible with Arduino IDE
trying to deal with lost class time: an assignment for next tue, then a crit on the 24th that includes the assignment?
Review Assignments
what went right?
what went wrong?
The “thing like a pot” is a rotary encoder
Finite vs. abstract state machines
finite: what we’re doing in class, fixed states and paths
abstract: can modify itself to adapt to changes in data.
What’s a state machine in nature with interaction?
Reactive state machines:
Hourglass timer – set time, start, stop, reset
Arcade game – attract / play / reward
gambling devices slot machines
Murphy bed attached to lights
Interactive state machines:
content predictors on Amazon/Netflix/eBay, “if you like…”
advertising predictors, “if you like xxx we want you to buy yyy”
microwave that can adjust cooking time based on humidity (I have one of these!)
traffic lights with IR detectors for EMS vehicles
Music instrument as state machine:

What if state machines were smart(er)? What are interesting problems for them to solve?
What are predictive states machines? console gaming turned in to physical gaming
auto-aiming / target tracking
catch a frisbee (dogs know calculus)
Can made predictions based on history/sensors? Your car notices you’re a sloppy driver (exhausted) and limits your speed. Duolingo detects you’re having vocab problems and changes your exercises (this is an ASM, arguably).
Visual changes in state
- Doppler shift in nature
- lives / health in a video game
- traffic slowdowns in Waze
- intensity of light => time of day
Mini-assignment for Thursday
post some interesting state machines to Looking Outward
