Has anyone made a 2 or 4 channel relay , and is that worked correct ?

hi I build a 2channel relay but this is same problem ( just one relay is working
it is serial manitor :
send: 2-2-0-0 s=255,c=0,t=18,pt=0,l=3,sg=0,st=ok:1.5
send: 2-2-0-0 s=255,c=3,t=6,pt=1,l=1,sg=0,st=ok:0
read: 0-0-2 s=255,c=3,t=6,pt=0,l=1,sg=0:M
repeater started, id=2, parent=0, distance=1
send: 2-2-0-0 s=255,c=3,t=11,pt=0,l=5,sg=0,st=ok:Relay
send: 2-2-0-0 s=255,c=3,t=12,pt=0,l=3,sg=0,st=ok:1.0
send: 2-2-0-0 s=1,c=0,t=3,pt=0,l=0,sg=0,st=ok:
send: 2-2-0-0 s=2,c=0,t=3,pt=0,l=0,sg=0,st=ok:

Hi @Reza

The start logs looks ok. Does the relay/node log say anything when you send a command from your controller. Any info from your controller?

Did you define your pins for the relay? A long shot but someone wrote it worked when they changed from 3,4,5,6 to 4,5,6,7 for some reason.
In most cases though it seems to be a power problem. Try changin your power source and see what happens.

What im most curous about at this point is to see the log from your relay when you send a on/off command for the two relays.

now I have a 2channel relay , i want test for 2channel but this is similar to 4channel .
in pics
in1=pin3 , in2=pin4 . the pin 3 is not working , now in2 is working , but if i change pin3 and 4 in1 will working. also i change 2 line of program to and wiring in1=5 and in2=4 but now pin4 dont work ....
#define RELAY_1 4 // Arduino Digital I/O pin number for first relay (second on pin+1 etc)
#define NUMBER_OF_RELAYS 2 // Total number of attached relays
now

Looks great - but taking steps here i want to know what happens in the serial log on your node when you send a on/off command from your controller?

@Reza we are kind of guessing in the dark right now. Can you post your sketch (as code, use the </> format button)

I change power supply and use a 5v 1A adaptor , but one relay is off always ( led off). and 2channel relay is not failure because when I change output pin 3 and 4 , that relay is on and work !!

This post is deleted!

[Reza]

:/ why delete your post ? :(

[sundberg84]

@Reza - ok communication looks good. My vote will be on power.
I would try to power the relay separately and see what happens (not from Arduino).

i test this . with a adaptor 5v 1A but dont any happen !?

[sundberg84]

@Reza From your images you are not - do you have another adaptor for the relay?

I disconnect relay from arduino and connect to a adaptor 5v 1A

[sundberg84]

Strange... im out of ideas at this point. Hardware failure?
Im not that good looking at the code, but I maybe someone else is.

:( thank you
this is strange for me too . pin 3 dont working . but pin4 worked . also if i change cable of pin 3 and 4 other relay working and pin 3 dont work
I change 2 line :
#define RELAY_1 4
#define NUMBER_OF_RELAYS 2
but so pin 4 dont work and pin 5 working....

@Reza,

I'm a noob at electronics and arduinos and have a wild imagination :smiley:

I had a theory but was unsure, so I decided to test it first rather than cause more confusion.

I know this is a place of sharing, but more than once I caused more problems when trying to help.

I don't want to bring some stupid idea into the fold.

I'll report back.
