LEDs do not light up
but if you run the script

import gpiozero # The GPIO library for Raspberry Pi
import time # Enables Python to manage timing

led = gpiozero.LED(11) # Reference GPIO17

while True:
   led.on() # Turn the LED on
   time.sleep(1)
   led.off() # Turn the LED off
   time.sleep(1) # Pause for 1 second

randomly light up red 3-4 diodes

microphones work fine
