# Spy Theme Playback Device ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/052/448/medium800/adafruit_gemma_spyThemesThumb.jpg?1521845761) When planning and gearing up for a secret op, every good agent needs some motivational spy music to set the tone! (Get it? _Tone_? Sorry, not sorry!)  With a Circuit Playground Express and its built-in speaker you can make your spy themes shine. Programming songs using MakeCode is fun! You can write your own tunes from scratch, or transcribe music. On Gemma M0 with an added piezo buzzer, we'll look at using CircuitPython to write music as well! ### Part: Circuit Playground Express quantity: 1 The microcontroller with the works [Circuit Playground Express](https://www.adafruit.com/product/3333) ### Part: Gemma M0 quantity: 1 Tiny microcontroller with a kick [Gemma M0](https://www.adafruit.com/product/3501) ### Part: Piezo Buzzer quantity: 1 Petite but loude [Piezo Buzzer](https://www.adafruit.com/product/160) ### Part: USB cable quantity: 1 6" A/MicroB [USB cable](https://www.adafruit.com/product/898) ### Part: 3 x AAA Battery Holder quantity: 1 w on/off switch and 2-pin JST [3 x AAA Battery Holder](https://www.adafruit.com/product/727) ### Part: AAA batteries quantity: 1 Alkaline 3 pack [AAA batteries ](https://www.adafruit.com/product/3520) You'll also use two M3 x 8mm screws and nuts to connect the piezo to the Gemma M0. - [Next Page](https://learn.adafruit.com/spy-theme-playback-device/code-music-with-makecode.md) ## Featured Products ### Adafruit GEMMA M0 - Miniature wearable electronic platform [Adafruit GEMMA M0 - Miniature wearable electronic platform](https://www.adafruit.com/product/3501) The **Adafruit Gemma M0** is a super small microcontroller board, with just enough built-in to create many simple projects.
