Overview

This project shows how to make a talking map, allowing the history contained within a map to be tangible and interactive. 

Using conductive paint, a Circuit Playground Express can be connected to different points on a map and provided with short audio clips to play when those areas on the map are touched. 

Parts

The Circuit Playground Express can connect to externally powered speakers via the audio jack, allowing you to play audio from the board at your preferred volume. 

Adafruit's USB powered speakers are excellent for this purpose, though you are welcome to use your own too.
