Step 1: Switch on a LED
Let's do the usual material "Hello World": switching a LED.
Just build as the photo shows.

Step 3: A Simple Flow
Here is the simple flow we will build with the graphical editor.
Step 4: Download and Install the Pi SDCard
Step 5: Access the Visual Editor
Use your web browser to access the visual editor using the network name you gave in the setup process.

Step 6: Build a Simple Flow
We will build a simple flow with the GPIO node.
Step 7: Edit the Node
Edit the node to set the GPIO port to use.
Step 8: Deploy and Test
just hit the deploy button and now, by clicking the Go button you can switch the LED on and off.
