In primul rand...scuze pentru intrebare...stiu ca e tampita :toimonster: Exista LED-uri care se descarca greu??? Si daca da ,imi puteti da niste exemple? Faza e k am de facut un afisaj cu vreo 70 de leduri si ideea e k nu pot face in asa fel k sa am semnal continuu pe un nr fix si vreau k sa introduc un impuls apoi sa anulez semnalu pe anumite diode dar ele sa ramana aprinse, sa se descarce greu!!!! 10x anticipat de respuns !!!bafta!!![/b]

NU.LED-urile nu emit lumina in lipsa curentului aplicat... :smt003 Temporizarea respectiva trebuie aplicata dispozitivului care comanda LED-ul in asa fel incat sa obtii efectul de ''memorare'' sau un anumit delay in raspuns.Deci trebuie sa spui ce fel de device-uri comanda LED-urile pentru ca acolo se modifica schema pentru a obtine efectul respectiv.
