  - Nädal 1-2: {{:et:projects:tudengid11:aruanne_myndisorteerija_i.pdf|}}
  - Nädal 2-4: {{:et:projects:tudengid11:aruanne_myndisorteerija_ii.pdf|}}
  - Nädal 4-6: {{:et:projects:tudengid11:euromyndid:aruanne3_2.pdf|}}

===== Eesmärk =====
Luua seade, mis suudab eraldada euromünte erinevatesse topsidesse ning kuvab seejärel lcd-le
kogusumma.


===== Idee =====
Müntide eraldamiseks otsustasime kasutada eraldusplaate, kus alumisele plaadile on puuritud 
euromüntide diameetritele vastavad augud ning ülemine plaat veab münte nende aukude kohal. Augud on järjestatud väiksemast suuremaks, selleks et vältida väiksemate müntide kukkumist suurematesse aukudesse.

Esimene prototüüp:
