-In order to run the demo, you will need to plug in your microphone or aux input into the respective jack on your Zybo. Plug your speakers/headphones into the Line out jack. Plug in your Zybo and power it on. Once the board is programmed, you can open a serial terminal (Such as TeraTerm) on your computer to receive status messages. Set up the serial port to connect to the appropriate port for your board, and for a baud rate of 115200.+==== 1. Set up the Demo ====
