Simple IoT LED Control (Turn a LED On/off Over the Internet With a Raspberry Pi)

What you'll be building

This tutorial teaches you how to turn a light-emitting diode (LED) on and off via the internet.


Raspberry Pi connected to the internetCircuit materials: LED, breadboard, wires, 330 ohm resistor

Step 1: Set Up the Circuit

Connect the LED to GPIO pin 4, and add a 330 ohm resistor in series.

Step 2: Run LimitOS on the Raspberry Pi

LimitOS runs alongside your existing operating system, and can be run via:

curl -sS | bash

Follow the on-screen instructions to register the device afterwards.

Step 3: Set Up the Device on the LimitOS Website

After registering your device, you'll be on the LimitOS website at . From there, go to your device by clicking "My Devices" and selecting your device. Then add pin 4 as a digital output, and you can then click the "on" or "off" buttons on the website to turn the LED on or off.
