mama CD 4017 and NE 555 IC deka dala hadana out put 5k thiyena knight rider circuit eke L.E.D. wenuwata Relay 5k dala circuit eka haduwa.Eth relays on welama thiyenawa.Wada karan na.Mama circut eke IC,Transister okkoma maru kala.Capacitors hitan maru kala.Mata ekata similar circuit ekak net eke hoya ganna bari una.Eth mama dakka me circuit board ekama wada karanawa..Meke relays use karanakota diodes danna onada
Kata hari plz kiyanna puluwanda mekata reason eka.mata hitha ganna ba.
Can some one plz help me.
C828 transister walin thamai out eka gaththe

macho relays valata power eka use kaarnava vadi ...
led valata ena power eke relay valata danna baha ...
onenam maam software ekak dennam .. eken puluwan circuit hadala vada karana hati balanna

Mama C828 wenuwata D 400 dala baluwa.Eth e wage.Machn mama Relay wenuwata L.E.D. dala baluwa.Eth wada na ne.Circuit eke awlak wage
Thanks 4 the help bro.

sorry machan reply ekata late una.

okkoma relays on welama thiyenawa de ?

oke diagram eka mata evanna puluwan nam ela.

 

[sugath]

oya circuit eke diagram eka danna.mama kiyannam problm eka.

 

[pavithra_uk]

bro try this trick,
1. disconnect pin 14 of 4017 ic and connect it to ground (-V supply) and check if relays off.

2. disconnect base pin (B) of any realy drive transistor, and check if that relay off.

Ok bro.mama try karala balala kiyannam.Mulin me circuit eka wada kala.Eth lines 2k hariyata off une na.Eth relay dammama thamai mehema une.Eth mama eka parak cap ekak athin push kalama wada kala.E welawe transister ekak pipiruna.Mama aith cap and transister okkoma dammama eth kalin wagemai wada na.Relay lines gannakota diodes danna onada.L.E.D.wage nemei ne mewa.

Bro mama base eka disconnect kala.e line eka off wenawa.mama relay ekata series karala L.E.D. ekak set karala baluwa.circuit ekata current eka denakota e welawe ara L.E.D. eka on wela off wenawa.Relay walata series karala diodes danna weida
sry for the disturb bro

Issaroma L.E.D hariyata pattuwenawada kiyala balala eelagata D400 through relay dala balanna.
relay walata kohomath series karala diod danna natnam backemf walata d400 pichchenna puluwan

 

[Elcid]

mama nam danne naha ban..
onna Bump ekak dunna

Thanks bro

machan machine eken circuit hadala wade kerene hati balane softwae ekak deepanko!!!!!!!!!!!!!!!!!

yeah broI should try that.Eth me circuit eka wada karanawa mama dakala thiyenawane.Me podi circuit eke awla hoya ganna bane mata.

Thanks bro.I will try that.

Here is the circuit diagram bro.
I still cant understand what happen.I know it will take a long tome to understand the fault.So doesnt matter bro.I will give up this one and.I will try a new common circuit tomoro.
Thanks bro
