Building the prototype

The final step is actually building a working prototype. This is where all of the hard work from the first three steps come together and you are able to see if the prototype works as expected.

All of us would prefer to skip the first few steps and go right to building the prototype; however, you will be more successful and damage fewer parts if you take your time and go through each of these steps when creating your prototypes.

Now let's see how we would go through these steps and build our first prototype. You will want to follow along and build this prototype yourself because we will be using it in the next couple of chapters as we learn to program the Arduino.
