Used EPS32 A2DP library to setup dev board as a Bluetooth audio sink and generate I2S data to send to audio amp. This library also allows for receiving raw incoming audio data via a callback function, I then performed an FFT on the incoming data and used the results to update the display.

Work left to do:

• Volume and pairing control via buttons
• Status LED to reflect pairing and battery status
• Audio playback from SD card
• Text and animations when not playing audio
