External hardware
You need 16 digital microphones, a clock generator (can be a raspberry pi, microcontroller, etc.), and something that recieves the I2S output (this can be a rapberry pi or most auido output devices). List external hardware used in your project (e.g. PMOD, LED display, etc), if any
