I am working on Smart parking project.
Here is my schematic.
I sent this to my professor and he said it is not right, i am not sure why. Also he said if i connect this to power source it will burn the source.
I am new at this so i really need help.
What am i doin wrong?

Take another look at the power supply to the LCD.
A reset button is handy for testing.
If the supply is no more than five volts, I don't see why the supply,
or anything else, would burn out.
I might have missed something.

It is about capacitor? i should put it between Vcc and gnd?
Dont understand what is wrong with reset.
Voltage source is 5V. Should i use voltage regulator?

Yes.

There is nothing wrong with your reset.
It is just that you need to turn the power off to reset the circuit.
If you add a push button you can do a reset while leaving the power on.
Sometimes that is useful for testing and programming.

No a five volt supply is fine.
I was just looking for reasons why your professor might be was worried.
He might think your supply is more than five volts.
