Hi
I am trying to make dog/cat feeder using load cell to control the motor trough relay.
My idea is when you press the button the food starts to pour in the bowl that sits on top of load cell, and it stops pouring when pre-set value is reach.
If any one has done simmilar project or is willing to help with scheme or code
I would realy appreciated. I m verry new in the field.
Consider some mechanical requirements:
- How will you start the flow of feed?
- How will you stop the flow of feed?
- Is weight or volume a better measure?
- How will you correct over weight/volume?
- How will the feed be sent to the bowl?
You might search (google) and find someone who has done exactly what you are trying to do.
More fruitful, usually, is to learn about the parts of your project, while learning about the logic of programming, so that mastery of using a load cell achieved separately from learning all about how relays are controlled and used in projects…
...would leave you in a good place to combine them so that the load cell might control the relay.
There will probably be more to it, but no time spent learning how to do the tiny pieces that will inevitably be part of the final code will be wasted.
pro tip: add the word arduino to your google search and zero in on stuff specifically tailored for this environment.

I just
arduino weighed cat food dispenser
and I could be busy all morning just browsing around to get an idea of what is involved and how people have gone about doing things like you want to do.

Search for topics using a loadcell. Absorb all You can.
Do the same for relay.
Combine the result.
The alternative is staying dreaming.
