Va rog ajutor la un temporizator!

Recommended Posts

Buna as vrea sa fac un temporizator care sa actioneze un releu, idea e urmatoarea cind pun in functiune sa declanseze releul si sa mearga 5 minute dupa care 2 minute pauza si apoi iar 5 minute si tot asa pina ce il opresc. daca se poate asa ceva astept orce sugestie si sfat eventual ceva scheme dar nu prea complicate. Multumesc anticipat pentru cei care ma vor ajuta.

Nu te chinui sa faci unul, nu merita. Mai bine cumpara un temporizator digital din comertz "priza programabila". E foarte usor de folosit, il poti adapta cum vrei si costa max40lei la VitaCom(Timisoara) sau chiar Selgros, Real, Metro. Eu folosesc doua si au abarerea de ~25secunde/saptamana dar sincronizandu-le la cateva zile nu se observa prea mult. Daca vrei ceva mai precis gasesti la 300$(sincronizare automata zilnica). :supz: Genul asta de temporizatoare au cam 10programe(ON/OFF) ce pot fi programate pe zile/ore/minute. Daca ai nevoie pentru un curent mare, potzi sa comanzi mai departe(cu el) alte relee. bafta...la cumparaturi :yawinkle:

uite solutia oferita de mine: un PIC16F84A care scoate pe PORT A 1logic la intervalele si pauzele cerute de tine. Uite si hex-ul::02000000402896:08000800CF00030E83128C00EF:0E0010000A0E8D00040E8E008A110A1243287B:100020009008031D14280800F930FF3E031D152811:100030000000900B14280800FA3090001020FA30CD:1000400090001020FA3090001020FA30900010201C:100050008F0B1C280800C030831681008316850191:10006000FF30831285008F001C202D308F001C2054:10007000831685018312850178308F001C202E287D:100080008A110A122B2883120E0E84000D0E8A008C:0A0090000C0E8300CF0E4F0E090086:00000001FFPIC-ul are quartz de 4MHz, iar alimentarea sa nu depaseasca 5,5V. Trebuie sa pui un tranzistor NPN cu baza in oricare pin de la portul a (A0, A1, etc.) prin care vei comanda releul.Daca mai e ceva spui.BR, xyz
