Make a bluetooth-activated talking dog collar for Halloween or just to show off at the park! This intermediate electronics project was inspired by Dug from the movie Up-- his talking collar translates his thoughts for communicating with humans. Using the Audio FX board and Bluefruit Micro, this project enables you to trigger sound samples through the Bluefruit LE Connect app for iOS and Android. The sounds are played through a mono amp connected to a mini metal speaker.
