Here are the motors that i am using, thanks so much leo..

Thank you:)

3Amp stall current... 11*3Amp...
I assume you're not using them all at once, but still.
Low voltage/high current motors are a poor match for small H-bridges like the L293.
But as this seems to be a toy project, go ahead and try.

Omg! Perfect your the best! Thanks so much!

24

do you know why here showing 12v power supply although these motors are 1.5 to 3v each?

thanks

25

Don't know.
Sales site with popups and sign-in crap.
Don't want to go there.

Hmm i see! Thanks!

Is there a way i can connect two wires to the same spot or hole in the breadboard?

27

No, but why.
There are five holes in a vertical row.
If you need more holes, then use a short (1") wire to connect two of those rows of five together.
Then you have eight holes for wires.

28

Because it shows that i need to connect two wires to the same spot which doesn’t make sense! If you have any ideas!

See the photo

If you know how i can connect the wire from v5 from arduino to the breadboard

29

Google how a breadboard works.
There are two long horizontal rows at each side of a breadboard, marked with a red and a blue line, that you can use for power and ground. Because you usually need to connect many wires to those.
And there are many 5-hole vertical rows, so you can e.g. connect four wires to an IC pin.

hey i am thinking of using L9110 hbridge because i dont want to put all the work on 1 hbridge, i just have a question how many l19110 can i connect to arduino mega? and any suggestions of how i should connect the wires?

More than 25.

Male<>Female Dupond wires.

Let us know how long a ~1Amp driver lasts with a ~3Amp stall motor.

alright cool! do you think i should use L298N instead of l9110s?

33

Both are about the same, and not really able to drive 3Amp motors.
But both drivers are lossy, and you might be able to get away with it on a 5volt motor supply.
Why don't you try it with ONE first, instead of 11.
