What you'll be building
This tutorial teaches you how to turn an active buzzer that emits a high-frequency sound on and off via the internet.
- Raspberry Pi connected to the internet
- Circuit materials: active buzzer, breadboard, wires
Step 1: Set up the circuit
Connect the active buzzer to GPIO pin 4.
Step 2: Run LimitOS on the Raspberry Pi
LimitOS runs on top of Raspberry Pi OS (Buster), and can be run via:
curl -sS https://limitos.com/run | bash
Follow the on-screen instructions to register the device afterwards.
Step 3: Set up the device on the LimitOS website
Add pin 4 as a digital output, and you can then click the "on" or "off" buttons on the website to turn the buzzer on or off.
