How to make an object shake/vibrate up down left right fast

Hello everyone! I am new to Unity and I am trying to figure out a few things. If anyone could help or point me in the right direction either information/tutorials/basic info on unity I would greatly appreciate it! The game I want to make is single scene. I am just wondering how I can make the shape object shake/vibrate. Is there a script for that or make a sprite/animation. If I do that, what is the code I can use to apply it? Thank you and ANY help or advice I would GREATLY Appreciate it!! Thanks.

iTween can be used to shake/vibrate your object. You can find iTween on Unity Asset Store.

ShakePosition(), ShakeRotation(), ShakeScale() methods may help you.
