It's helpful to other forum members who may do a search and find this thread while trying to solve a similar or same problem, to explain how you fixed it.
sure i will...im trying to draw the whole working schematic again .
and will upload them here..please wait for some time .
You haven't posted a schematic yet.
Fritzing can draw schematics. You need to select the schematic view.
hi. I have already posted the schematic in the question and it need some changes and once i draw the whole schematic i will post here. please give some time.
i havnt used any capacitors for the shift registers. and im using tha 16 channel 5v Low level trigger relay module.
You posted a Fritzing breadboard diagram. Now post a schematic.

Perhaps you should consult some application notes for the logic family you're using. It will explain to you why they are necessary.

I have been testing the project for last few hrs and i don't see any issues till now...and everything works flawlessly to me. is it really necessary to add bypass capacitors?
Because you've been lucky so far.

I guess you never followed my suggestion to go and find out?

Did that possible inspire your user name? Good choice btw.
@anon57585045 im using 74HC595 8-bit Serial to Parallel Shift Register IC.
@10.2 in the below pdf is what you telling me about right?
is their any schematic on how to add capacitors with shift regsiters and Im using like three of those..soo should i add one for each or 1 can do the job for all?
Yes.
Yes. Section 10.2 of the pdf.
Yes

this is my complete project schematic(link below) @anon57585045 @PaulRB @gcjr @er_name_not_found
please can you check and update me if i need to fix anything.
also I added 0.1uF capacitors with each shift register.

Please post a schematic and we will check that for you.

@PaulRB doesn't post #37 look like a schematic? i used bread board to make it look much better and cleaner
I said in post #26 that you are posting breadboard diagrams and asked you to post a schematic. You gave a like to that post.
In post #23 I said you can use Fritzing to make a schematic from your breadboard diagram. Switch from breadboard view to schematic view. All the components and connections will be carried over from your breadboard view. You can arrange the components in the most convenient way, a schematic does not need to reflect the physical layout of the components. You can use power and ground symbols in many places so there are fewer wires criss-crossing each other. In these ways you can draw a much better and clearer representation of your circuit than any breadboard view. That is the power of schematics!

@PaulRB sure i will try to draw that.
its real pain making the schematic. fritzing just force closes randomly...will try to make.
