Raspberry Pi with Node-RED: A Comprehensive Guide

Goals

What will the students learn in this course?

Basics of Node-RED will be learned which is how to create an IoT application using a visual interface. They will learn to install and set up Node-RED on Raspberry Pi, Arduino, and ESP32. Understand how flow-based programming works. Connect your Raspberry Pi, Arduino and ESP32 devices with Node-RED. Understand how to read sensor data, such as temperature, humidity, etc, together with the actuation part with LEDs and motors.
MQTT, HTTP and all such communication protocol; Device to device message transmission through MQTT using the services of Node-RED.
Real-time data, charts, and graphs in designing interactive dashboards in Node-RED
Practical work projects: home automation, weather stations, smart gardening systems.
Conclusion: All the students will be so well aware with proper on-hand experience to build up their very own IoT solution using Node-RED, and the above hardware is used.

Prerequisites

What are the requirements or prerequisites for taking your course? 

• Some familiarity with Raspberry Pi, Arduino, or ESP32 boards is beneficial.
• If students are new to these platforms, they can start with basic tutorials to understand their components and usage.
• A basic understanding of Internet of Things (IoT) principles will be useful.
• While no prior experience with Node-RED is required, students should be open to learning a visual programming approach.
• Basic knowledge of connecting components (sensors, LEDs, etc.) to these boards is essential.
• Enthusiasm for hands-on learning and building real-world IoT applications is key.
• Curiosity and a willingness to explore different project ideas are encouraged!
• This course is designed to guide beginners through the process, so even if students don’t meet all prerequisites, their curiosity and willingness to learn will go a long way!
