Rui here,
I hope you are doing well!

I’ve just added 4 new units to the Home Automation using Raspberry Pi course.

Here’s the quick links for Module 11:

• Unit 1 – Introducing the Arduino
• Unit 2 – Installing the PubSubClient Library
• Unit 3 – Connecting the Arduino to the Node-RED Nodes
• Unit 4 – Controlling Outputs with Arduino using MQTT

If you have any technical questions, please post them here: https://rntlab.com/forum

In this next Module, you’re going to learn how to control outlets with the Arduino board, read sensors and user other nodes  in the Node-RED UI

Have a great weekend,

Rui Santos
