I just purchased 2 SG90 servos, along with a pan-tilt setup. However, after setting it up, and running, the servos are vibrating when rotating. Please look into the following video.
Please wait - I just uploaded the video so Gdrive is processing it.

Your link does not work.
Show us a good schematic of your circuit.
Show us a good image of your ‘actual’ wiring.
Give links to components.
In the Arduino IDE, use Ctrl T or CMD T to format your code then copy the complete sketch.
Use the </> icon from the ‘reply menu’ to attach the copied sketch.
The link doesn't work for some reason.
You can post code, autoformatted in the IDE and pasted using code tags, </>, here.
Schematics is valuable.
please wait. gdrive is processing the video. I don't know how long it will take.
now you can check the video

Also, when running the Example sketch from Arduino, the servo do skip some rotation and keeps vibrating.
If you continue to run two servos from the Arduino you may damage the Arduino or your PC.
Things like servos and other high current loads must be powered by their own dedicated power supplies.
These power supplies need a common GND to the Arduino GND.
I believe your version runs best at 6v but will probably work fine at 5v.
Suggest you use a 6v/5v @ 2Amp power supply for this application.
oh ok. Is this because the power is too low to run? Because when running a single motor it do skip some rotation just like a random wheel slip
Suggest you use a regulated 6v/5v @ 2Amp minimum power supply for this application.
A real wiring diagram, schematics will likely tell things that would help us....
The only power I see looks like being the USB, and servos powered from the controller board. That's no, no. Separate servo power supply is recommended.
do I need to plug it into arduino directly (12V adapter ) or have to use Breadboard for that?
Any extra power source you would recommend for this project?
A 4xAA battery pack will work for two SG-90 servos, if the batteries are fresh. Otherwise use a 6V 2A(minimum) AC adapter.
and I can then power the HC-SR04 from arduino without any issue right?
Yes.
will that solve the wheel slip of the motor?
