Guest digitekovi Posted May 8, 2007 Share Posted May 8, 2007 Salutare! Caut o schema care sa fie o bariera in infarosu, adica imediat ce se intrerupe transmisia intre receptor si emitator sa se aprinda un led. Mersi mult. :yawinkle: bogdnam: se muta la "scheme" Link to comment Share on other sites More sharing options...
Abram Burel Posted May 9, 2007 Share Posted May 9, 2007 Ai putea folosi orice emitator si receptor de telecomanda. Transmiti periodic o comanda. Receptorul functioneaza ca un monostabil retriggerabil. Daca receptioneaza comanda intr-un timp dat, atunci reseteaza un contor, altfel contorul expira si genereaza alarmarea. Niste scheme simple sunt la http://www.sixca.com/eng/articles/remote/index.html Link to comment Share on other sites More sharing options...
