Arduino LCD Stopwatch Firesport Schematics Code Eagle

Stopky pre požiarny šport cez Arduino


  • Stopky vhodné sú vhodné pre Dobrovoľný hasičský zbor (DHZ) pre tréningové meranie útoku tímu.
  • Meranie času na stotiny sekundy, programová logika sa vykonáva každých 10ms, čo je 0.01 sekundy.
  • Logika systému sa vykonáva každých 10, alebo 100 milisekúnd podľa softvéru. (10 milisekúnd - presnosť na stotiny, 100 milisekúnd, prenosť na desatiny sekundy)
  • Čas je v reálnom čase vypisovaný na LCD znakový displej rozmeru 20x4, alebo 16x2, program je plne kompatibilný.
  • Funkčnosť systému:

  • Stopky sa odštartujú tlačidlom (môže byť nahradené signálnou pištoľou)
  • 2 spínacie kontakty umiestnené na terčoch sa aktivujú pri spadnutí terča, zastaví sa ľavý/pravý prúd na stopkách.
  • Posledné tlačidlo slúži na vynulovanie času - reset času, nové družstvo, nový štart tímu, neplatný štart.
  • Stopky žiadnym spôsobom nemôžu nahrádzať certifikovanú časomieru! Meranie je orientačné. Presnosť závisí od použitého kryštálu Arduina.

    Hardvér pre projekt:

  • Arduino Uno
  • LCD displej 16x2 alebo 20x4 s I2C prevodníkom
  • 4x spínacie kontakty
  • Možno doplniť o buzzer (hlásič), ktorý pípa pri ukončení útoku
  • Spotreba: 20mAh pri 5V napájaní

    Stopky v akcii:

    Hasičské stopky na stotiny sekundy
