Ce este ceasul binar ?

Spre deosebire de un ceas obișnuit cu numere sau cu limbă, mai există o variantă de ceasuri ce reprezinta ora și minutul în format binar. 

Pentru a construi un ceas binar simplu vei avea nevoie de câteva componente de bază:

  • O placă Arduino;
  • Un ceas de timp real (RTC);
  • LED-uri;

LED-urile ceasului binar se vor aprinde în funcție de codul binar. Dacă în codul binar vei întâlni un „1“ logic atunci LED-ul va sta aprins sau stins dacă este vorba de un „0“ logic. Ceasul de timp real este un circuit integrat specializat în a menține timpul, adică funcționează asemănător cu un ceas. RTC-ul este util deoarece placa Arduino nu este destinată pentru a face acest lucru. 

Cum se construiește un ceas binar ?

Pentru un ceas în format binar care indică ora și minutul vei avea nevoie de 13 LED-uri, o bucată de carton cu găuri pentru fixarea fiecărui LED, 13 rezistoare de 220 de Ohmi, fire pentru conexiuni, butoane pentru setarea ceasului binar și o cutie. Ceasul se poate alimenta fie dintr-un alimentator extern sau dintr-o baterie. Fiecare LED se conectează la pinii digitali ai plăcii Arduino.

Cu alte cuvinte, vei conecta cele 13 LED-uri la pinii 13 – 1. LED-urile se aranjează sub forma de coloane și rânduri. Pentru ore vei avea 2 coloane: prima coloana alcătuită din 2 LED-uri iar a doua coloana din 4 LED-uri. Pentru minute vei avea 2 coloane: prima coloană alcătuită din 3 LED-uri iar a doua coloana din 4 LED-uri.

Atenție! Nu uita ca fiecare LED se înseriază cu câte o rezistenta de 220 de Ohmi…
