Simple IoT LED Control via Raspberry Pi

Requirements

• Raspberry Pi connected to the internet
• Circuit 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:

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 LED on or off.
