"It’s a fairly simple setup based around note recognition. When certain notes are played in a specific sequence, the Raspberry Pi detects the tune via a microphone within the Amazon Echo-inspired body of the build, and triggers the action related to the specific task. The small speaker you can see in the video plays a confirmation tune, again taken from the video game, to show that the task has been completed."
