Computer de Bord Auto

/*Proiect COMPUTER de BORD AUTO |

-afiseaza tensiunea de incarcare cu averizari la valori anormale; |

-afiseaza temperatura exterioara cu avertizare la inghet (temp. < 5 grade C); |

-afiseaza temperatura apei din motor; |

-afiseaza temperatura uleiului din motor; |

-comanda aprinderea unui LED rosu si pornirea unui COOLER atunci cand val_digitala. APA sau ULEI > 90 grade; |

-afieaza in procente si printr-un bargraph luminozitatea ambianta; |

-comanda aprinderea unui LED albastru(avertizare) si a luminilor (LED alb) la intenitate luminoasa scazuta; |

-afiseaza numarul de litri din rezervor cu avertizare pe LCD atunci cand nivelul este sub 7 litri; |

-afiseaza autonomia autovehicolului pe baza numarului de litri de combustibil ramasi |
