Getting into the holiday spirit, in a Charlie-Brown-meets-Adafruit sort of way.
Each light is either a red or green LED on top of an appropriately colored twisted pair of solid-core wire. A resistor is soldered in-line on one of the wires, cutting down on the space needed on the protoboard. The lights are driven by the PWM pins on a DC Boarduino. This board is perfect for this application as power is easy to get (9V wall adapter), and it is temporary. Additional animations can be added easily enough in the code.
If you’ve ever struggled to use a solderless breadboard with an Arduino, you understand how frustrating it can be!
This clone acts just like an Arduino, and works with the latest Arduino software. For many projects it can even be preferable! The kit includes all parts necessary, the assembly is straightforward and well documented.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
