Star Wars music sketch on GitHub – https://gist.github.com/nicksort/4736535

In this final episode of 2018, I will show you how to take the projects you have built using an Arduino Uno and “shrinkify” them down to an ATmega328 chip. This will allow you to make a permanent version of your project without using up one of your precious Arduino boards.

The ATmega328 is the microcontroller chip at the heart of the Arduino Uno. It is available in several packages, we will focus on the common 28-pin DIP (Dual Inline Package).

You only need a handful of components to turn an ATmega328 chip into a fully-functional Arduino Uno equivalent. It’s much cheaper and a lot smaller, allowing you to build a permanent version of your design onto a small circuit board.

I will also show you three methods of programming the ATmega328 chip, after all an Arduino isn’t very useful if you can’t upload a sketch to it!

To illustrate my point I will put together a very simple yet cute “music box” using an Arduino Uno, and then we’ll move the project onto an ATmega328. It will be of particular interest to Star Wars fans as the “music box” plays “The Imperial March”. If you have an old Darth Vader or Storm Trouper toy it would be neat to build it into it!

I cannot take any credit for the sketch I used to create the Star Wars music box, the code was written by Nick Sort about 6 years ago and is available on GitHub – https://gist.github.com/nicksort/4736535 . It’s an excellent example of making simple music with the Arduino.
