Actions, Events and Filtering
For Actions, Events and Filtering assignment, I made a very simple game that uses a flex sensor and a player only can solve it by a specific way of bending it rather than just bend normally.


Here is the description of this assignment.



I simply build the hardware part using Arduino and software part using Processing that are connected through serial communication. In this game, which is similar to unlock the padlock, a player should bend the flex sensor a specific way and the specific time. For example, Step 1. bend forward and keep it more than 5 seconds but less than 8 seconds, Step 2. release and keep about 3 seconds, Step 3. bend backward and keep it more than 7 seconds.

(cubic equation graph from wikipedia)


Actually, my initial concept was that using a differential of a equation such as a cubic equation, however, my flex sensor was quite unstable so I needed an extra work(ex, averaging). Therefore,  I just use the sensor value and the time as a variable.


the lock will not be solved when a player bend it without knowing specific steps.



the lock was solved by the specific way described above.
