| Ako program funguje:
| |
| Projekt pozostáva, ako už bolo spomenuté, z LED diódy, LCD displeja a tlačidla. Najprv stlačíme tlačidlo, čím sa celá vec spustí. Potom sa rozsvieti LED dióda a zhasne až po stlačení tlačidla. Ide o to, aby sme ho stlačili najrýchlejšie, pretože na LCD displeji sa zobrazí informácia o tom, že ako rýchlo sme boli v milisekundách. Túto časť sa mi bohužiaľ z technických dôvodov nepodarilo nahrať na video. Pravdepodobne niečo nebolo v poriadku s mojím LCD displejom.
