Our work contest this year was to decorate a mini stocking. I
chose to add lights and music using Adafruit parts. The lights are
individual NeoPixel LEDs, the audio comes out of a mini speaker
(https://www.adafruit.com/products/1890) driven by a 2.5W Mono Amp
(https://www.adafruit.com/products/2130). The smarts of the stocking is a
Teensy board (https://www.adafruit.com/products/2756) running the OctoWS2811
library for the LEDs, the Audio library for the music (DAC output to the
amp), and the Snooze library (with one pin setup for capacitive touch
wake-up) for power savings. A 3xAAA battery pack was used for power. I
thought it turned out really great and it looks super cute.
Teensy 3.2 + header: Teensy 3.2 is a small, breadboard-friendly development board designed by Paul Stoffregen and PJRC. Teensy 3.2 brings a low-cost 32 bit ARM Cortex-M4 platform to hobbyists, students and engineers, using an adapted version of the Arduino IDE (Teensyduino) or programming directly in C language. Teensy 3.2 is an upgrade over 3.1! Teensy 3.2 is a drop-in replacement upgrade for 3.1 and can run any sketches designed for 3.1. (read more)

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.
