The Adafruit Grand Central is arguably one of the most feature-rich boards Adafruit produces. Adafruit is planning some great tutorials to showcase using the Grand Central in many ways. But what about a simple "I just got my board and want to do a quick demo to kick the tires?"

Rather than code some "blink the LED" or "Hello World" project, here is a quick project only using a few parts which will have you building a fully functional soundboard in about ten minutes.

The ability to do this partially lays with the powerful processor on the Grand Central but has everything to do with being able to run CircuitPython. This easy to use yet powerful code is loaded onto the board by saving a file onto the flash drive, which shows up when you plug the Grand Central into your PC / Mac / Linux / Chromebook via a USB cable. It is that easy, no software framework to set up, no compiling, no compatibility issues. It really allows you to plug, copy, and go!

This project will get you started with the code and eight public domain/creative commons sound files and you can make this project your own by changing things up.

Power

For a demo project, USB power for the speakers and the Grand Central is perfect. If you really want to take this on the go, an optional a cell phone recharge battery with two USB ports would help.
