This example polls a sound sensor and sends a noise alert to a RGB LCD display and turns on an LED when a loud noise is heard. The system returns to monitoring after 5 seconds.

On the GrovePi+ or GrovePi Zero, connect a LED to port D3, a sound sensor to port A0, and a RGB LCD display to the IC2-1 port.

This project was created as a Nerves app. To start your Nerves app:

  • export NERVES_TARGET=my_target or prefix every command with NERVES_TARGET=my_target, Example: NERVES_TARGET=rpi3
  • Install dependencies with mix deps.get
  • Create firmware with mix firmware
  • Burn to an SD card with mix firmware.burn
You can’t perform that action at this time.
