So Im working on a project which works perfectly fine on my tinkercad but when i copied everything on a real arduino and with the my components it doesnt turn on. My teacher told me maybe is its something to do with my power supply but im not quite sure how to do it. Can someone teach me on how to? here is my circuit in tinkercad
You need an external power supply for those motors. The Arduino cannot supply enough power for even a single motor. I guess a 5V with 2~3A would be enough.
The Arduino can provide power for the LCD. But in your diagram, it is not provided with any power.
do you know how i could like connect the battery? I tried doing it in the tinkercad and nothing would on im not quite sure though how. I wanna try using irl but im kinda scared that it might blow up or smthing. im still starting arduino so im not quite sure
What battery? You did not mention any battery before and no battery is shown in your diagram.
Leaving out important details like this is frustrating for people who want to help you. Provide them with all important details when you ask for help.

I’m sure it will work better - you’ll like it.

Even when you add supply, be aware those breadboards do not necessarily transmit power through from one centre boundary row to the next...

I tried your diagram in tinkercad and it does not work at all.
Please show the real diagram that you claim works?
