Abstract:
The goal of this project was to create a system to wirelessly broadcast an audio signal from a
computer to a set of speakers using Wi‐Fi. This allows one to play music files from a computer
and have the sound come out of any speakers that are in range of the wireless network. The
ideal use case for this product would involve the ability to have a computer in one room
processing music files while multiple speakers throughout the house are actually playing the
music. This would be particularly useful in a party setting where one would like to keep a
computer safe in a locked room while still being able to use it to play music. Additionally, if a
party is there are sets of speakers in multiple rooms, they can all be synced to the same audio
source. The major components of the system are the microcontroller receiver module (an
ATMega 328p) and the computer program that sends the packetized audio data.
