I see a dot in the green line.
I attached a highlight of what i mean.
That means 2 wires are connected at that point.
If you do that on a breadboard, Fritzing! will connect the wire to the breadboard as well and make an invisible connection to the pin under your wire.
That pin happens to be in the GND rail of your breadboard.
If you're going to use the other modes (so not breadboard mode) of Fritzing!, then you'll see a connection of the green wires to the GND rails.
This is of course not what you want.
But if you're just going to use the sketch as a guide for your jumperwires, you're good.
Also if you already connected all and made your sketch afterwards, it will be good and you'll be ready to test.
Don't forget to connect the capacitors.
Have a look at "blink without delay".
Did you connect the grounds ?

You're almost good to test.
I've just loaded your Fritzing! sketch and the short in the above post is not shown in Fritzing! so never mind that.
There's no other strange connections either so that looks good to me.
But i do see another problem.
In your sketch, the 2nd L293D doesn't have a connection to VCC1 drawn.
So the upper middle motor won't run if that is indeed the case.

Succes with your robot arm.

Thanks for the warning. I've modified robotic arm without connected inverters and it works good. Now I done solution to connect photosensors like indication change moving the robotic arm.

I think that it is very beneficial project for my bachelor thesis.

Also you have helped me a lot and to facilitate the work of the project.

I was pleased to read your posts. :-)
