If you work with an Arduino this is a step that you should always take to prevent you having to pay for another one.

The reasons you should do this:

It will prevent your work surface for being scratched.
It will prevent the Arduino from slipping and potentialy falling.
And most importantly it will stop the Arduino from short circuiting if you placed it on a metal surface and frying the components

Step 1: You Will Need

You will need:

4 x Small Rubber Bumpers: http://amzn.to/2fsg1zT

What I recommend:

- Arduino For Dummies (very helpful when learning code): http://amzn.to/2feAN0P

- Arduino Projects For Dummies: http://amzn.to/2eaVsC1

- Amazon Prime 30 Day FREE Trial (so you can get your products tomorrow): Amazon Prime

Step 2: Add the Bumpers

Find four suitable places on the underside of the Arduino in places where it will be stable and remove the paper backing and place them on.

You have now stopped your Arduino's contacts from touching the work surface, well done.
