This project has two parts: the first part is analog and teaches the basics of making circuits using a battery pack, LED, and a do-it-yourself switch. The second part is digital and allows you to program your own light show!
To keep this overview short and sweet, we are focusing on the digital part only. To build the analog circuit, check out the build instructions below.

For the digital circuit, start by making a ground pad. Your ground pad will connect all negative, or ground, alligator clips.
Use your ground pad to connect the LEDs to the Arduino board as shown in the diagram below.
That's it! Snag our code (in Attachments section below) and use our custom Excel workbook to program your lights in different sequences, you can even choreograph them to your favorite (holiday) song!
You can add up to six (6) LEDs on the Arduino digital pins 3, 5, 6, 9, 10, and 11.
P.S. We love when folks hack and modify our projects, if you do so we would love to see! You can tag us on social media (search for HackingSTEM) or feel free to share your creations here.
And of course, please reach out if you have any questions or ideas for us!
